OPINION
¶ 1 Daniel John Smyers appeals his convictions for two counts of furnishing harmful items to a minor. Ariz.Rev.Stat. (“A.R.S.”) § 13-3506 (2001). For reasons discussed below, we reverse his convictions and remand the case for further proceedings consistent with this opinion.
FACTUAL AND PROCEDURAL BACKGROUND
¶ 2 Eleven-year-old Desia 1 knew Smyers as a friend of her father and paternal grandmother, and so, with her grandmother, she visited Smyers at his house in March 2000. When Smyers and Desia were alone during that visit, Smyers took the opportunity to show the girl pictures on a computer screen of a man and a woman engaging in sexual intercourse.
¶ 3 The matter was reported to the police, to whom Smyers subsequently admitted that he had been alone with Desia. The officers found on Smyers’ computers images consistent with Desia’s descriptions of the pictures she had seen. Smyers was charged with two counts of furnishing harmful items to a minor.
¶4 At a pre-trial hearing, the prosecutor asked the court to decide pursuant to Arizona Rule of Evidence (“Rule”) 609 that, should Smyers testify, he could be impeached with a 1996 conviction for attempted child *481 abuse, a class 3 felony, in connection with the death from starvation of his six-month-old son. Smyers responded that the conviction was not probative of the charged offense but that, if the conviction were admitted, it either should be “sanitized” to indicate only the fact of a prior conviction or the full nature of the offense should be told the jury. The court compromised:
... Since essentially the evidence may be a credibility battle between whether the jury believes the young child or Mr. Smyers, his credibility is central to a determination of this matter.
So if Mr. Smyers chooses to testify, I will allow him to be impeached with the fact that he has this prior felony conviction. I am not sanitizing it. So the name of the offense, the Court, the date, and whether he was assisted by counsel, all of that will be allowable. The class of the felony will not be allowed to be discussed, nor will the facts of the offense. We are not going to talk about ... what he did to the other child, the starving or whatever. The fact that there was a jury trial or a plea and the facts of those cases I find under [Rule] 403 are unfairly prejudicial, and the prejudice outweighs the probative value. So we won’t talk about the facts of that particular' incident.
¶ 5 Smyers chose not to testify. He was convicted as charged and appealed.
DISCUSSION
¶ 6 Desia recounted how Smyers had kissed her on the lips, tried to “French kiss” her by sticking his tongue in her mouth, and hugged her by placing his hands on her “butt” and pulling her against his body. Rule 404(b) prohibits the admission of evidence of “other crimes, wrongs, or acts” to prove a person’s character, but it permits the admission of such evidence “for other purposes, such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident.” Smyers argues that the trial court erred by admitting evidence of his “other bad acts” towards Desia. Our standard of review is whether the court abused its discretion.
State v. Roscoe,
¶7 At the outset, the prosecutor must establish by clear and convincing evidence that the defendant committed the prior aet(s).
State v. Prion,
¶ 8 The trial court found Desia’s testimony about Smyers’ approaches to be sufficiently clear and convincing evidence. It ruled that the incidents were probative, citing Rules 401 and 402, and that the probative value outweighed the danger of unfair prejudice, citing Rule 403. The court then offered to and later did give a limiting instruction to the jury consistent with Rule 404(b). We find no abuse of its discretion in the admission of these acts of Smyers against Desia.
¶ 9 We did, however, order the parties to file supplemental briefs to address a second issue: whether the trial court committed reversible error in its admission of Smyers’ prior conviction.
See State v. Curry,
¶ 10 When reviewing a ruling on the admissibility of a prior conviction, this court will reverse the trial court's determination if the court abused its discretion,
State v. Bolton,
¶ 11 It has been settled by the United States Supreme Court that a defendant’s decision not to testify at trial serves to waive his right to challenge on appeal the trial court’s ruling on the admissibility of his prior conviction.
Luce v. United States,
¶ 12 A defendant may be impeached with a prior conviction for “the purpose of attacking [his] credibility” according to Rule 609(a) “if the court determines that the probative value of admitting this evidence outweighs its prejudicial effect.”
2
To the extent that the prior conviction is akin to the charged offense, the potential for prejudice is stronger because the “similarity to the charged offense may lead to the unfair inference that if defendant ‘did it before he probably did so this time.’ ”
Bolton,
¶ 13 In Brunson, the charges against the defendant included possession of a controlled dangerous substance and possession of a controlled dangerous substance with intent to distribute. Id. at 1087. Before trial, the prosecutor said that, should the defendant testify, the prosecutor intended to impeach his testimony with the defendant’s pleas of guilty to possession of a controlled dangerous substance, possession of a controlled dangerous substance with intent to distribute and theft. Over the defendant’s objection, the court ruled that the prior convictions would be admissible for the purpose of impeachment, and the defendant chose not to testify. He was found guilty as charged, and, on appeal, he argued that the court had erred by not sanitizing his prior convictions. The New Jersey Supreme Court held:
[I]n those cases in which a testifying defendant previously has been convicted of a crime that is the same or similar to the offense charged, the State may introduce evidence of the defendant’s prior conviction *483 limited to the degree of the crime and the date of the offense but excluding any evidence of the specific crime of which defendant was convicted. That method of impeachment will insure that a prior offender does not appear to the jury as a citizen of unassailable veracity and simultaneously will protect a defendant against the risk of impermissible use by the jury of prior-conviction evidence.
Id. at 1092.
¶ 14 The trial court ruled that it would allow Smyers to be impeached with his prior conviction. Refusing to sanitize the conviction, the court allowed the jury to be told “the name of the offense” as well as “the Court, the date, and whether he was assisted by counsel,” but it would not allow the jury to be told the class of the felony or “the facts of the offense,” finding that to permit mention of the circumstances surrounding the conviction would be “unfairly prejudicial” and that “the prejudice outweighed the probative value.”
¶ 15 The trial court’s conditional admission of Smyers’ prior conviction constituted eiTor in several respects. First, the court confused the standard of Rules 403 and 404 and that of Rule 609(a). Second, admitting the prior felony conviction in evidence but neither sanitizing the offense nor allowing the nature of the conviction to be adduced added to the prejudice inherent in the admission in evidence of a prior conviction. Third, the court did not recognize the importance of the defendant’s argument with regard to the disclosure of the nature of the prior conviction.
¶ 16 The trial court said of Smyers’ prior conviction that the facts “under 403 are unfairly prejudicial and the prejudice outweighs the probative value. So we won’t talk about the facts of that particular incident.” It thereby confused Rules 403 and 404 with Rule 609. As this court recently wrote:
Rule 609(a) allows the impeachment of a testifying defendant with a prior conviction if the trial court determines “the probative value of admitting this evidence outweighs its prejudicial effect.” In contrast, Rule 403 allows the trial court to exclude evidence if “its probative value is substantially outweighed by the danger of unfair prejudice.” Thus, under Rule 609, the defendant is not required to demonstrate that the prejudice of the impeachment is “unfair” or that the prejudice of the impeachment “substantially” outweighs its probative value.
Beasley,
¶ 17 Next, by telling the jury the name of the offense but not its context, the jury was allowed to speculate about possible similarities between the conviction and the charges. This served only to increase the prejudice to Smyers.
¶ 18 In
United States v. Jimenez,
¶ 19 The trial court’s ruling regarding Smyers’ prior conviction similarly “exacerbated” the prejudice to Smyers. The jury, upon hearing only that Smyers had a prior conviction for attempted child abuse, could well have speculated that the earlier abuse involved sexual misconduct. This makes it altogether possible that Smyers could have been convicted of furnishing harmful materials to a child at least in part on the improper basis that, if he committed a sexual offense against a child “before he probably did so this time.”
Bolton,
¶ 20 Indeed, the decision whether to have the prior conviction sanitized is to a signifi *484 cant degree that of the defendant. As the court wrote in Brunson, ■
[a] defendant wary of jury speculation about the unspecified offense may introduce evidence of the nature of the prior conviction. Sanitization of prior-conviction evidence of similar crimes merely limits the scope of the prosecution’s cross-examination of a defendant to the date, degree, and number of similar prior convictions. A defendant may choose to waive the protection afforded by that limitation.
¶ 21 This does not mean that there is no limit to the extent of the revelation of the circumstances surrounding the prior conviction. The disclosure should not reach collateral matters or serve to retry the conviction, but should be limited in the trial court’s discretion to the nature of the offense of which the defendant was convicted as described, for example, in the document charging the offense or in the verdict. As the court said in United States v. Harding,
The prosecutor may use a prior conviction to impeach a witness. Whether the witness be the defendant or a third party, the scope of the examination is strictly limited in order to avoid the confusion which may attend the trial of collateral issues, and also to avoid unfairness to the witness. The rule that it is error to inquire about the details of prior criminal conduct is so well established that such error is cognizable despite the absence of any objection by defense counsel.
¶ 22 The basis on which Smyers made his decision thus was critically flawed. The Court in Dace necessarily presumed that, in deciding whether to testify, the defendant would be acting upon proper guidance from the trial court regarding the use of the defendant’s prior conviction to impeach his testimony. If, however, the trial court’s ruling is erroneous, the defendant cannot make an informed and reasoned decision concerning the consequences for him of the application of Luce. If, as a result, the defendant is prejudiced, as was Smyers, the trial would not be fair, and the eonviction(s) would have to be reversed in favor of further proceedings.
¶ 23 The state suggests that, if the trial court erred in how it admitted evidence of Smyers’ prior conviction, it was harmless.
See Bolton,
CONCLUSION
¶ 24 We reverse Smyers’ convictions and remand for further proceedings consistent with this opinion.

. Additionally, the crime must have been one "punishable by death or imprisonment in excess of one year under the law under which the witness was convicted” as was true of Smyers’ prior conviction or one that "involved dishonesty or false statement, regardless of the punishment.” Ariz. R. Evid. 609(a).
