Mexican Coin? need ID

[Leon]

Hello all, I have found a 1933 bi-metal Mexican coin with " N$ 1 " on one side, and " ESTADOS UNIDOS MEXICANOS " around the rim, and an eagle sitting on a cactus with a snake in it mouth in the center ,on the other. the outside ring is what looks like silver, and the center looks to me like brass or bronze...
I have had any luck finding a site that you can lookup Mexican Coins, other then new ones.
Any help in ID'ing this coin would be greatly apprieated...
Not sure denomination it is?

Thank you!
