Portugal

someone from portugal north area who can help me identify and evaluate several old coins

Have a read here https://en.numista.com/forum/topic71935.html and post cropped photos showing both sides of the entire coin ... I'm sure someone will be able to help with identification.

Or grab a coin identification app. Two I use are Coinoscope and Maktun.

After identification take a look at the Numista pages for the coins, and then come back to ask specific questions about valuations if any of the coins are especially interesting.
