This is an 1872-Pi O Mexico 10 Centavos, in what I would say is in Filler - AG condition. The coin has significant wear, and the details are pretty hard to identify. However, the date is clear enough to see it is 1872, and the back of the coin in picture 6 barely shows the'O' in what it would be'Pi O'.
Mexico only had 4 mints for this year with'Pi O' being the only mint with an'O' at the end, which must make it this coin. This is a very hard to come across key date coin with a mint of only 16k. If you have any questions, feel free to ask, and please examine the pictures carefully on the coin you'll receive.
