I have a card that is almost identical to the 2005 Upper Deck - Trevor Hoffman #168 card (http://www.tradingcarddb.com/ViewCard.cfm/sid/1884/cid/377848/2005-Upper-Deck-168-Trevor-Hoffman), but instead of being marked #168, it says #SD10. Is it possible that it is part of a seperate Padres set? (similar to the 2006 Topps Detroit Tigers set (http://www.tradingcarddb.com/ViewSet.cfm/sid/124034/2006-Topps-Detroit-Tigers), for example, which has a similar system for the numbering of the cards. Can anyone point me to this set on this site, or tell me if it does not exist, or if it's some sort of misprint...? Thank you.
