I posted a pic of a coin that I am unable to identify in my album.
Please take a look and let me know what you think....
It's very large, about the same size but bigger and maybe a tad slimmer than a US silver dollar.
Has the look and feel of Silver.
Has 1780 on it?

Cost that pup? What's a 1915 1 mark (germany) worth.... probably MS65-70. Looks like it just come from the mint,, with some very nice subtle toning around the rim.
Is it silver,,, sure look's like it.

As always,,
thanks

I can't help with the latter but I can with the former.

It is a Maria Theresia Thaler which has been minted with the 1780 date until present times:

You need to get into the contest area more often. I just gave away one recently.
