Answer
Hi Frank,
Both of these coins are Mexican. The 1844 coin is from the Guanajuato mint. Prices range from $15 for a well used coin to around $100 for one in excellent shape. Typical examples that I see tend to sell for around $25-$35.
The earlier coin is Spanish colonial, but made at the Mexico City mint (the M with an O over it). You did not mention what year this coin is, and that can have a significant bearing on the value. For the majority of dates, one in good shape without damage or other problems is right around $100. In rough shape it can be as low as $25, while in mint condition they are rare and would be in the $200 to $300+ range.
If you would like to post a follow-up question with a clear photo of the coins (this site only allows 1 photo per question) I can give you an exact grade and value.
Thanks for the question! =)
