BobJim is right. If it's even a PSA 8 set, then the Dr. got a bargain. VCP has very little data on recent 3-D sales since there haven't been many. They have sales data for the Clemente 10 that sold last December in Mastro ($30K) and some prices for the three common ones (Fairly, Davis, and Maloney).
The only tough card (Clemente isn't considered tough) that there's data on is the Swoboda that sold in October on eBay for $1,703 (PSA 3).
I would think that a PSA 8 set would go for over $30K easily on eBay. The break-up value would be more than that since the Powell, Flood, and Stottlemyre would get a LOT of interest.
