I sold Hal my '25 Gehrig Exhibit for 10k. I think it resides in a 6 holder now. It was a 5 when I had it though it was obtained raw from a Mastro Auction, for 2700'ish in '97-'98. I think it was described as NRMT-MT when I bought it so I was a little disappointed in the grade.
It was a record sale to Hal at the time though, so I Have that going for me !!
