May 20 Market Update: Tim Duncan 1997 Topps Chrome RC PSA 10

Tim Duncan 1997 Topps Chrome RC PSA 10 has been ON FIRE. Two weeks ago, we posted about the KG Topps Finest RC PSA 10 discussing the significant increase in value 1990’s rookie have seen. Well, this one is no different; since 2020, it has increased 439% in value.

There have been 65 auctions to sell on eBay over this time period, starting at ~$215 in mid-January and the most recent value being $1,168 on May 18. As for the PSA population, 2,291 PSA 10’s out of a total of 6,464 graded (35%). In your opinion, is this card increasing too fast or was it so undervalued before that it is justified?
