Artist looking to BUY bulk leftover WORLD coins for 32" x 58" table

Hello dear coin collectors.
I am a hobby artist and I have for some time considered covering my 32" x 58" table desktop with coins and possibly also bank notes underneath. I will cover them all with table top epoxy.
"Problem" is that looking online I can buy bulk bags of coins but I do not really feel that is the best way to go to get a good selection for cheap.
I am NOT particularly interested in the collection value, I am just interested in the looks and variation, I would prefer as many DIFFERENT WORLD COINS as possible for my project. The coins do not have to be in great condition or valuable, but the prettier the better of course.
Therefore I am asking to buy "leftover coins" in bulk, enough to cover my table.

I have a 30-pound box of world coins that might be perfect for you.

Might be more coins than you need, but it's a great variety of designs, countries, metals, and conditions.

You can buy the box then pick and choose your favorite coins.

Let me know if you're interested. Price negotiable.
