I paid $75 for my Tino Martinez token from that set. It all depends if an avid Jeter collector wants/needs it for his set. It would probably go for a pretty penny if you were to sell it considering I've seen 2 Tino Martinez, a Paul O'Neill, but never a Jeter.
It's a pretty cool card. Considering the token hasn't been used in the NYC subway since 2003 (phased out in favor of the debit-like MetroCard), it is a bit of a collector's item, even to the non-baseball fan. The particular style of token used for the Subway Series inserts was only in use until 1980.
If so I'd put it on ebay where you'll almost certainly get more. Not being dispariging in any way of the members here but if the limited visibility you get here gets an offer of $375 they'd of course be willing to bid that on ebay and your visibility goes up 1,000 fold and all you need is one or two of them who are willing to pay a premium for that card.
