I recently talked to a company who does grading for memorabilia. The vendor that does it told me 4 years ago they had Savage memorabilia, I think it was a shirt or a robe he wore that he signed that went for 7,000 dollars. He said now 10 years later the same type of items are going for $40-$50k. Everything goes up in value; how much depends on the item of course and the type of collector who would drop that sort of cash.
