Hi, I have two marbles and I just don't know what they are. The first one has a matte finish. It's not glass. There are no pontil marks and it is not signed. It measures 7/8". The second one also has no pontil marks and no signature. This one isn't glass either and it has a glossy finish. It has crackling throughout the middle band. It measures 1 1/4". I don't know if these are modern marbles or older ones. Any help would be greatly appreciated. Thank you!
