Do any of you guys know anything about Billiard Balls? I am hosting a church missions yard sale, and one older gentleman brought three sets of pool balls. One looks fairly run of the mill (I stickered them @ $20) but the other two look to be of a higher grade. One in particular looks like it might be made of Bakelite or some similar material and I am guessing these are quite old. At any rate, I think there may be better venues to sell these at than a yard sale, but I don't know the first thing about how to determine what we have here. Any thoughts? TIA.
