Chunk of 1724 - 1 Batzen from Basel

High I have one of these coins - regrettably with a hole in the top when used as a necklace - so I don't suppose it's worth much.

I could not find it on Numista to catalogue it .. Can someone point me in the right direction .

Thanks

It is not in the Numista catalog yet so you can add it yourself, here is some further information of the coin out of the KM catalog:

Thanks for the info if only some idiot hadn't drilled a hole it -it might have been worth something
