In practice it may reliably go in one direction for some issues and the other way for others, but I'd be interested in the main effect (i.e., who is more lenient on average).

You should be able to get a federal grant to fund this experiment.

Bah, I can't get federal grant money for my real research. Most of us probably already have hundreds of pre-war cards in our collections, but even if you were starting with no cards at all you could get enough together for adequate statistical power for a few thousand dollars. The average sale price of the last 25 raw pre-war cards on eBay was about $7.50.

Not a problem. Send me the cards and I'll submit them with my return address.

I understand PSA and SGC are both out sourcing now!!!
