Hi guys, as the title suggests, I am wondering if you guys could provide me with some advice/insight on a couple Mexican coins.
1) What would you consider a fair price for the two coins, a piece?
2) The 1870 20 pesos looks fairly nice, expect for an area on the reverse. There appears to be a gash/gouge on the left side scales of justice that extends to the "I" in veinte. What would cause that?

Thanks in advance!
