during early 80's. the 1000 piso gold coin is not worth 1000 piso. it fell below face value. of course the price is still a little premium over 1000 piso. i should have buy some during those years. but i wasn't. instead i got a lot of uncirculated 1975 big marcos 5 piso - nickel. around 2,000 pc. a lot of 1 piso, 25 sentimos, 10 sentimos, 5 sentimos and 1 sentimos. original plastic bags and rolls. total your guess. i came to american with only 400 unc 1 sentimos. because it was light. it's aluminum. it's been 27 years. time goes fast. i only saw caesar became one of the top guy in your coin club there. the rest. i don't know. some maybe pass away.
