Back about 6-7 years ago I received a mexican coin from a friend who visited Mexico. This was WAAYYY before I was into coin collecting. Unfortunately I lost it, and havent seen it since. Well today I found it. I was going through my crawl space looking through all my old toy boxes from when I was a kid, just to see what kind of interesting stuff was down there. I came to one of the last boxes and found all kinds of things like old transformers, power rangers, and even my old Super Nintendo system. I was just about to put everything back when I saw a coin sitting at the bottom of the box. I grabbed it and to my surprise it was the coin that my friend gave me. Now, after all these years I still have no idea what to call it. It has a picture of a dragon on the obverse and it says $5. At the bottom it has the date 1980. On the reverse it has what looks like another dragon with a snake in its mouth, and says ESTADOS UNIDOS MEXICANOS. I think its like 5 pesos or something? I dont know the denominations in Mexico so thats my guess. Anyway, I just thought I'd share my highlight of the day. Hopefully it didnt bore you lol.
Nice that you found your missing coin! I am missing my box of 1909 vdb cents that had about 50 of them in there
A picture would help. Judging from your description, it sounds like the 1980 copper-nickel 5 peso piece with Quetzalcoatl on the obverse, and (not a dragon but) eagle and snake on the reverse. 27 mm wide? Worth somewhere between 25 cents and $2.25 (brilliant uncirculated), but looks pretty.
