Here are 5 Steve Nash 1998-99 Topps Chrome cards that I bought off eBay recently.
I believe that this is Steve Nash's 2nd year Topps Chrome card because I do not believe he had a card in the 1997-98
Topps chrome set.
I had checked the 97-98 Chrome checklist on tradingcarddb.com and it looks like there was no Nash Chrome card produced that year.
So being that Steve Nash's rookie card is in the 1996-97 Chrome set, this would be a 2nd year Chrome card.
