Thanks for waiting! I LOVE these Chinese coins, because there are so many types of them. I would estimate I have around 3,000 now.
The fron tof this coins tells us it was minted in 1736. The back tells us where in China. The particular markings identify this one as minted in Peking, by the board of revenue - which was the main government mint. They were widely circulated, and actually used until the late 1800's. Still a good find though. The value, as someone pointed out, does not amount to much, I would estimate $1-3 in its condition - but hey, you broke the century barier though!
Good find!
