Dang, where to start? I've got lots of coins from the 1600s and 1700s- more than I think anyone here wants to see. I guess I'll pick out a few of my favourites, but nothing compares to that Siberian Typeset. >< I've been wanting a Siberian coin for a while now; but they're expensive in decent grades!
1/2 Reale, 1701 Carlos II. Potosi Mint. Posthumous Issue, as Carlos II died in 1700. Unlisted variety.
Sixpence, George II. 1758
5 kopeks, Catherine the Great. 1763.
twopence, George III. 1797, my favourite handleable coin.
