Anything from the 1700's This is the only one I have so far but I'm working on getting a few others for my type set.
Mecklenburg-Schwerin, 1789 Schilling. I've been buying a lot of old German coins recently and have another 13 from the 1700s which I have scanned in but not yet edited the images. I'll work on it soon and try to post them all as I do them.
Here's three of mine. Not the highest grades, but they're mine. 1787 Fugio, 1795 LC S-76a (R-5), 1788 Massachusetts;
Sadly I don't have any 1700's, but I must say that I love that variety. I can only imagine that the engraver was thinking "whoops, I better make the clouds bigger to fix my mistake" or something to that extent.
Here is my first Large Cent that I picked up from Tom Deck (great guy by the way). It's a 1798 - S-169 R3. I also have this coin. It was purchased from a fellow CoinTalk member. It's a 1788 MA One Cent coin with period. It's got a rather large planchette flaw, but I still love it!
