However, contradiction of collateral facts by other evidence is not permitted, as its only effect would be to show that the witness is capable of error on immaterial points, and to allow it would confuse the issues and unduly prolong the trial. State v. Kimble, 140 N.C. App. 153, 167, 535 S.E.2d 882, 891 (2000) (citations and quotation marks omitted), cert. denied, 360 N.C. 178, 626 S.E.2d 833 (2005). While the denial of a conviction may be contradicted by extrinsic evidence from a public record, the facts surrounding prior convictions will normally be collateral, and extrinsic evidence is inadmissible if used solely to contradict the witness’ denial of such collateral matters. See State v. Dalton, 96 N.C. App. 65, 70, 384 S.E.2d 573, 576 (1989) (<HOLDING>); State v. Monk, 286 N.C. 509, 517, 212 S.E.2d
