Nope. Copper-nickel. Not silver. Do this long enough, and you'll get so you can spot silver straight off, just by the color alone. And, on the flipside, stuff that isn't silver. My "silver sense" is not infallible, but it's probably 98% accurate.
It looks like 2551 in the Thai calendar, so 2008, I believe. Thai coins are not my strong suit by any stretch of the imagination, but I think it is a 2551 (2008) 1-baht coin. Edit- I see it would be nickel-plated steel, not copper-nickel, if that is the case. Give it the ol' magnet check.
Awesome find! Tokens are pretty cool. I actually found a Chuck E' Cheese token once in a quarter roll :O
You found that in your couch?!?! Did you lose it at some point or did you buy the couch used and it was from the last owner?
The Panama money is 1:1 with US coins, same size and weight and can be spent as US money, it also fits all of our vending machines. This is the same as a quarter. Bahamas also. Our currencies are interchangeable. Of course people think you are trying to scam them with a foreign coin, but these coins are legal tender here, just as ours are in their countries. So it's just easier to put it in a parking meter, or whatever in order to spend it. Unless it's an old silver Panamanian coin, I don't bother collecting them.
Are you talking about coins? Or cash currency? The don't make Panama cash anymore. They use the US dollar, and the coins are made up to 1 Balboa. The coins are specifically designed to be the same size and weight to fit our vending machines, parking meters, tolls, etc. The nickels, dimes and quarters are interchangeable. Not sure about the pennies halves and Balboas.
