Lately I have been reading up on Mexican pattern coins. Because of monetary reform in 1992, many "patterns" were actually produced in large numbers, but were made obsolete before they could enter circulation. This ATLAN $1000 coin is very affordable, because of its awkward maybe-a-pattern status:

Then we have the 1986 SUD peso... 33 are known to exist, but catalog price is $65! On
ebay, they seem to go for a bit higher. To be honest, I didn't want to tell people about this because I really want one, but the Internet is all about sharing knowledge:

General Jose Morelos appears on the "normal" pesos of 1986, and as a leader during the Mexican Revolution (against the Spanish), he issued these crude "SUD" pesos (for his Army of the "South", in the Spanish language):

I hope none of you are motivated to buy one, but this is a really cool coin: not only is it a nifty replica of a popular Mexican revolutionary issue, but it was issued by the very person who appears on the "normal" peso type of 1986. Imagine the
Franklin half having the design of the Fugio Cent on the tails side!
But we have another pattern to look at. Mexico kept experimenting with circulating silver coins, even as the peso became more and more inflated - because if you're the largest silver producer in the world, go for it! It ended with the $100 coin in 1979... or did it?!

Yes... there is a pattern silver $100,000 coin out there. Considering there were about $3,300 pesos to the USD in 1990, this would have had a face value of around $30 at the time... and even today, this would convert to N$100, worth about $8 right now. It's doubtful that it would have circulated, and the new pesos that replaced it were also made in silver, but this would have contained about a troy ounce.
If you're still

over Mexican revolutionary coin designs brought to life on modern issues, though, you're in luck... in 2011, Mexico produced a series of bimetallic $100 coins, featuring faithful replicas of Mexican coins, from the Spanish colonial pillar dollars to the 1914 "who's that guy on the horse" peso:
