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.
Good luck getting the bank to count it for you. My bank would only accept bulk coins like this if they were counted out into separate coin bags - which they would give you. Then they can check by weight.
Yeah, it's been that way for decades. You just empty the jar/bag into the machine and it sorts/counts everything automatically, and then you can transfer the amount to your bank account.
When I was a kid I used to love this. We'd go sell stuff at flea markets and then take the bag of coins to the bank. Watch number go up, yay.
USA here, my bank credit union does this. Much better than taking it to the Coinstar at the grocery store which is actually the same machine but charges a fee to use.
It really depends on the ratio of pennies and nickles to quarters and dimes. I helped my father in law sort a jar of coins he had collected from his parking lot at work, I estimated like $150-200 but there were almost 50% quarters and dimes and it turned out to be nearly $1000.
Interestingly, quarters and dimes have about the same value per weight. As in a pound of quarters has the same dollar value as a pound of dimes. You could weigh the jar and get a min max estimate and know it's somewhere between if it was all quarters or all pennies
