I've offered a number of rare and high grade Juan Gonzalez cards in the last few weeks, including a Precious Metal Gems and others. This is the rarest of all. Offered as a redemption, limited to 20 and the redemption expired 12/31/2002. In all likelihood, there are well under 20 examples with examples unredeemed. I actually couldn't find a record of one sold. Actually a rarer card than the PSA 10 1993 Refractor I have yet to offer for sale.
