It would seem that the Singapore 50 cent coin is very similar to the Philippines peso. Size, shape, texture, color, etc. Easily mistaken in a drawer full of change. Kind of like American quarters and Canadian quarters. (Funny side note: While here an English guy with the company took me out to lunch, and we were talking about coins and currencies and what not. I forget why, but he mentioned that he sometimes has leftover Canadian coins when he goes to the US from Canada. I told him that Canadian coins with strikingly similar US counterparts can easily be spent in the US if the cashier isn't paying close attention. He seemed surprised. Foreigners are weird.)

And, apparently, I have received such a coin from a drawer full of change at one of my recent trips to a store:

Fifty cents when I was supposed to get a whole peso (dollar)? I hope I haven't been ripped off...

1 Singapore dollar = 33.2360971 Philippine pesos

Not bad, so that means I made money on this transaction:

0.5 Singapore dollars = 16.6180485 Philippine pesos

Minus 1 peso for the change I was supposed to get:

15.6180485 Philippine pesos

Which in actual money equates to:

15.6180485 Philippine pesos = 0.370709999 U.S. dollars

For free! I hope I don't accidentally spend it as a peso and negate this profit.
