Do you have an ebay reference?
Are they blankbacked?
Most of the proofs I have from the Toppsvault are blankbacked - my understanding is that PSA won't grade blankbacked proofs.

<< <i>I think proofs would not be graded. I spoke to PSA a few months back about grading some '88 Topps cloth and was told that they wouldn't grade anything that was experimental in nature and not produced in quantity for distribution. I think the proofs would fall into this category as well. And if even if they did grade them, you obviously couldn't use them in your registry sets b/c it wouldn't pass the quantity test.
