POLITZ, Chief Judge:

Jesse Aguirre, Sr., convicted upon his guilty plea of possession with intent to distribute in excess of 100 grams of heroin in violation of 21 U.S.C. § 841(a)(1), appeals the sentence imposed. Finding no error, we affirm.

Background On March 4, 1992, authorities arrested Aguirre in possession of approximately eight ounces of heroin. He was indicted for possession of in excess of 100 grams of heroin with intent to distribute, in violation of 21 U.S.C. § 841(a)(1). Invoking 21 U.S.C. § 851, the government supplemented the indictment with an enhancement information, alleging a 1976 Texas heroin distribution conviction which became final in 1985. Aguirre moved to quash the information, contending that the state obtained the earlier conviction in violation of Batson v. Kentucky,1 and it therefore could not serve as the basis for sentence enhancement.2 Aguirre entered a guilty plea under an agreement in which he reserved his right to challenge the enhancement. The guilty plea was accepted and Aguirre was sentenced to prison for 120 months plus a term of supervised release. He timely appealed. Analysis On appeal Aguirre renews his arguments that the district court erred in refusing to quash the enhancement information and, notwithstanding prima facie evidence of a Batson violation at the 1976 trial, relied on the conviction there obtained in imposing an enchanced sentence.^[3] He acknowledges that, due to its nonretroactivity, Batson could afford him no relief from his 1985 1 476 U.S. 79 (1986). 2 In connection with this motion, Aguirre produced evidence that the prosecutors used eight of their ten peremptory challenges to dismiss prospective jurors with hispanic surnames.

conviction in federal habeas corpus proceedings.^[4] Relying on Burgett v. Texas,5 Baldasar v. Illinois,6 and Bourgeois v. Whitley7 for the proposition that unconstitutionally-obtained convictions cannot support sentence enhancements, Aguirre urges, however, that we must deny any prospective effect to his Texas conviction. Although initially facially appealing, we find this argument ultimately unpersuasive.

In Burgett, the Supreme Court considered a direct appeal from a murder conviction where, in support of enhanced sentencing, the state had placed before jurors evidence of a prior uncounseled conviction. Noting the fully retroactive effect of Gideon v. Wainwright,8 the Court found Burgett's prior conviction presumptively invalid and held that the state could not use such a conviction either to support guilt or to enhance punishment in a subsequent prosecution.^[9] Later cases adhering to Burgett prohibit reliance upon Gideon-violating convictions at sentencing,10 and use of such convictions at trial to impeach the defendant.^[11] In Bourgeois, we recognized that the Burgett principle extends to later use of convictions invalid on different grounds and found invalid a sentencing proceeding in which the trial court considered a conviction by a nonunanimous six-member jury.^[12]

Subsequent authority, however, suggests that Burgett, its progeny, and Bourgeois are not dispositive of the instant case. In Lewis v. United States,13 the Supreme Court found no sixth amendment impediment to a firearms possession conviction under 18 U.S.C. § 1202(a)(1)14 predicated upon a prior Gideon-tainted felony conviction. The Court there noted that it had not endorsed an absolute prohibition on use of uncounseled convictions,15 distinguishing Burgett, Tucker, and Loper, noting that

[i]n each of those cases, this Court found that the subsequent conviction or sentence violated the Sixth Amendment because it depended upon the reliability of a past uncounseled conviction. The federal gun laws, however, focus not on reliability, but on the mere fact of conviction, or even indictment, in order to keep firearms away from potentially dangerous persons.^[16] Lewis suggests the close relationship between the right to counsel and the reliability of criminal proceedings as the driving force of the Burgett line of cases.17 Obviously, convictions obtained through nonunanimous six-member jury verdicts -- at issue in Bourgeois -- raise similar concerns. Batson violations, however, do not. Racially motivated peremptory strikes at best marginally implicate the reliability of fact-finding in criminal trials.18 Batson protects against racially motivated peremptory strikes principally because they "'cast[] doubt on the integrity of the judicial process' . . . and place[] the fairness of a criminal proceeding in doubt."19

Additionally, post hoc identification of Batson error presents difficulties we do not find in either the Burgett or Bourgeois contexts. By contrast to the minimal inquiry required to determine whether a defendant had or waived counsel in prior proceedings, or whether a prior conviction resulted from a unanimous jury verdict,

the finding of intentional discrimination in use of peremptory challenges is a finding of fact that "largely will turn on evaluation of credibility." Years after trial, the prosecutor cannot adequately reconstruct his reasons for striking a venireman. Nor can the judge recall whether he believed a potential juror's statement that any alleged biases would not prevent him from being a fair and impartial juror.^[20] Thus, the inquiry into possible Batson violations tainting a prior conviction -- particularly in a case such as this one, involving 17-year-old peremptory strikes -- offers little potential for a meaningful result.

Racially motivated use of peremptory strikes only marginally implicates the reliability concerns underlying the Burgett line of cases. Further, unlike Burgett, the instant case does not involve enhancement on the basis of a prior conviction presently subject to collateral attack.^[21] Finally, the difficulty inherent in after-the-fact identification of Batson violations counsels strongly against requiring inquiry into such error in pre-Batson convictions.^[22] We conclude and hold that pre-Batson convictions, although potentially tainted by Batson-violating use of peremptory strikes, may properly support sentence enhancement in subsequent prosecutions.^[23] In view of this holding, Aguirre's remaining contentions are mooted.

The sentence imposed by the district court is AFFIRMED.
