1964 was a BIG year for Mexico medals - a lot of different medals were issued that year.
Your medal is Grove #900a (silver).
Grove does not list metal content on any medals. He just lists them as bronze, silver, gold, etc. He does imply that most medals struck in silver were made with a high content of silver.
The medal should be 24.91 grams (but I have found that some medals vary a bit from the weights listed in Grove).
This is a mint issued medal (Mexico Mint), and is listed as 1,000 minted. This sounds like not very many, but is a common mintage. Since Mexican medals don't have a LOT of demand, this means that it would not be considered rare just based on mintage. They also issued 250 pieces in gold. Grove, in the preface to the book, expressed some doubt as to the accuracy of all of the mintage figures he obtained from the Mexico mint, so the mintages listed are not guaranteed to be accurate.
If it were me, I would start it in an auction at around $15-$20 and see where it goes. Personally, I might bid as high as $25 on it if it were not damaged (I am a little concerned about spots around the 1964 date, but that could just be the quality of your photos). You might get more than that, or less. That is the cool thing about auctions.
The prices of Mexican medals vary greatly, and personally, I never know how much one will fetch. I have purchased some for amounts I consider cheap, while at other times they sell for double, triple or more, than what I would think they are worth. Some sellers way over price their medals, and as a result, never sell.
I have seen your medal listed on
ebay at least three times in the last 5 years (when I began keeping track of them). This means, to me, that they are not "rare" in the sense of availability. Two of them were in apparent better condition that yours (or had better photos) and one was in worse condition (rim dings, for example).
I hope this information proves useful to you.
