I would like to explain to people why these coins are worthless. To say that they are no longer accepted as currency is not an answer. A coin can still have intrinsic value. And people want to know what it is. Can someone PLEASE tell me the intrinsic metal composition of a 1000 peso 1988 mexican coin. I would like to know their melt value. I would welcome reference to your info (book or article you read that stated the metal content of these coins). Thank you very much. UncleKin
There are actually several 1000 peso mexican coins, some even made of gold. But the common 1988 1000 peso is made of an aluminum bronze alloy which would be worth a few cents at best. The gold version, struck in Proof, 1 oz, is worth bullion value. So which one do you have ?
I believe mine is one of the cheap one. It is a gold color with what looks like a gal on the obverse or a guy with a hood pulled over his head. Not certain which. But the coin is a gold color and quite heavy so would not think it is aluminum. I will put an image up if interested. -Ken
Here is the image. Blurry as I just took it with one hand. But one can see the obverse. http://www.wildlanders.com/members/aws/temp/peso1000.jpg I put it on my cheap scale and it weighs about 1/2 ounce. I would like to find out the copper content or any other metal. Even if only 15 grams, it would be worth the copper for melt value. And one might be able to buy these for much cheaper where, as I understand it, people throw them away. So I am looking for a specific metal composition in percentages. -ken
What's the pointing about the potential metal value when seperating the copper out from aluminum is a costly labour? Perhaps the cost of seperating such metals will even exceed what you have there unless you have more than a few tonnes of them.
gxseries, There is a reason I am asking for the actual percentage composition. One is to see who really knows their stuff. In addition, until one actually knows their subject one cannot fully benefit from it. And so I am asking about Mexican coin composition. But this is true of all things. As for what I have or will find out, I am not going to tell you my secrets... -UncleKin
The coin is aluminum bronze of that there is no doubt. Exact composition is not listed in the Krause catalog, so that's about all you're gonna find out.
The coin shows Juana de Asbaje (Sor Juana Inés de la Cruz) who was a 17c nun and poet; she is also depicted on the current 200 pesos notes. The Schön catalog just mentions an "Al-N-Bro" composition - that would mean Cu92 Al06 Ni02, maybe a little more copper and a little less aluminum ... Christian
Not really. That $1000 coin is worth 1 peso in today's currency, and that would be $0.09 ... Also, in order to get that 1 peso for it, you would have to take it to a bank or service center of the central bank. Christian
If it has Juana de Asbaje on obverse, then it is aluminum-bronze. Not worth much for its metal value, but if it is in XF -AU condition, maybe US$3.00 -$4.00?
