This one's the dead give-away. Even on the most worn specimen if 1860 or 1861. Look at the big pictures on my varieties website. Easier than looking at Freeman/Gouby books.
I’m going for F20, 2+G, I think there is a signature on the bust, and the lower margin of the bust and rose looks right, and the colon after ‘G’ of DG points to a tooth.
But I won’t be upset if it’s F28, fingers crossed!
Either way a rare coin.

The thing is I don't even think the vendor is trying to be untruthful, I just think he is being stupid, a bit like the person who slabbed the coin in the first place.
