Around 1 Inch my marble collecting friend (plus or minus)--they vary quite a bit- 1/8" inch or even more.
At the size that you show--this one is just not an Atmo.
It sure looks like one though. Too Small--still cool.
Once a marble hits the high marks for money it is often repeated--these Atmos are going very high.
Marble--On!!
Welcome Dwasson80 to the oldest marble ID sight on the web-- or on earth for that matter.
"TheMarbleConnection".
We will all help to ID your marbles.
Just keep them well cropped and show several sides of them.
Three or four at a time is acceptable--just send us some nice clear images.
Marble--On!!
This one is a stone--not glass.
I am thinking "Tiger Eye" here. A very pretty marble--or sphere.
Nice images for sure!
Size is always important for a marble ID.
@Alan may have an opinion here as well.
Marble--On!!
Ok--lets slow this one down a bit.
I, and many, appreciate both of you and your posts regarding marbles.
I was the one to say start the bidding @5$.
These may bring $50--who knows?
Lets just get along here and put it behind us.
Marble--On!!
