Now I know that you never clean your coins and that 99% of the time doing so won't even increase the value. But I just got some old Mexican coins and look like they were buried, so they have a lot of dirt and gunk on them. Would going over them with a wet rag be okay?

Your coins, you can do what you want..... as long as you don't want to sell them for 'UNC' coins afterwards 0:)

I'm just more concerned as to damaging the coin or lowering it value

you will ruin any value the coins may have retained from burial- cleaning coins always lowers it's value

Can you define "old Mexican coins"?

Old being like 1950-1980, not any rarities. Also "buried" was more of a figure of speech, I was more or less saying they were covered in dirt and and powder from oxidized metal. I had to wipe away for dates. Could even a rinse off destroy the value?

If these coins aren’t rare or valuable, and have already been in circulation, then your probably not going to hurt them any by washing and drying them. — In my opinion.

Just don’t polish them and then try to sell as “Brilliant Uncirculated.”
