These are 2 vintage, VITRO, Tiger Eye marbles. The marble on the left has a .625" diameter and as-made slightly out-of-round. I consider it to be in Mint Minus condition and I see as-made natural bubble pops and a natural cooling crease and as-made under the surface annealing fractures.The marble on the right has a .598" diameter. I consider it to be in Mint Minus condition and I see one 1/32" nick and a couple pin head nicks and natural bubble pops and a natural cooling crease.
