The jar looks like it’s made a glass, which is common and probably worth only a few dollars.
Jars of coins, however, are much more rare, and could be worth a lot more. It’s kind of hard to make jars of coins. Maybe if you melt them together. Sounds like craftsman work.
If you have a picture of your jar of coins – maybe this was an upload of the wrong jar? your glass one? – please post it so we can assess the worth. Thanks.
Hey, just tossing in a comment here, I think this post is a good post!
