MMM

MMM Colorado are sought after pieces, however, very little information about this old refiner has been uncovered. The first gens only come with an MMM Stamp and typically are sub 5 oz. Later varieties, assuming they are related and the same refiner, have the MMM with the Colorado stamp. These range from sub 3 oz up to 10 oz from what I’ve seen. Looking for more information on these.

Top example a chunkier pour and bottom a flat pour, visibly larger. Same layout and stamp placements, however.
Incredible patina forming on bottom flat variety. Love this piece.

Pictured here is the MMM with Colorado stamp.

Really cool hallmark.
Just a bit over 2 troy oz. Interesting to see stamp in grams.

I received a new MMM first gen image today from Jon M. Thanks for sharing this sub 2 oz example

Very cool little bar!
