Alan used to buy quite a lot from a local legend collector and dealer I was friends with. Always treated him well
One time I was setup at the old Cranston RI show when it was in Warwick.
I had an older 50s personalized Mantle ball I had picked up at a paper show. . I was confident but as a customer was looking, he walked by and randomly blurted out " nice old Mick".Helped me sell the ball for 100.00.
. I only paid 50 at least
