Thanks, guys. Gxseries - I like your icon. That proof Soviet 150 Roubles has to be platinum or palladium, since at that time silver commems were in the 1-5 Rouble face value.
Here are some of my Mexicans. I wouldn't go into early colonial stuff (cobs, pillars, portraits), but start with my favorite area - War of Independence:
This is a double-counterstamped issue, using the same punch as KM#289, except with a 1 Reale host, instead of 2 Reales listed in Krause:

My first coin from Durango Mint was this 181(2) 8 Reales.

Which piqued my interest in the early years of this mint and led to my next acquisition - 1815 Durango 8 Reales. Specific Gravity is a little high on this coin, making me believe that another, heavier metal, was mixed with silver to create the alloy, which happened often during the War times:

This next piece is another double-counterstamped issue with Morelos and Chilpaz stamps. The host coin is a cast 1809 8 Reales.

My all-time favorite is this Gadalajara 8 Reales from 1814. It's so crude - it's beautiful


Out of Republican coinage - I'll just post a couple of Cap'N'Rays:
1826 Zacatecas Mint:

1843 Mexico City Mint:

1849 San Lois Potosi Mint:
