1987 Mexico ANA Medal / Coin / Pattern? 0

[gmarguli]

Anyone know what this is? I assumed it was for a 1987 ANA convention in Mexico, but they were held in Atlanta and Charlotte that year. 

Has the Mo mint mark, so it was struck by the Mexico City mint.

Under the mint mark is Laton 85/15 which apparently indicates that it is brass (85% copper and 15% zinc). I find it odd that they would list the composition as that is usually reserved for coins with gold or silver in them. 

Weight is 4.4 grams.

It appears that the Mexico mint did issue special coins for the 1987 Atlanta ANA convention, but all I can find on them is they are silver onzas.

I wonder if they had a press set up at the convention striking these.

I didn't go to that one that year.

Cheap brass medal made at the Mexico City Mint for sale in the 1987 ANA bourse and by mail. I believe there was also a 0.999 silver version with the weight and metal on the date side. Might be of interest to some medal collectors.
