>/pmg/, I just bought $20 FV of halves at my LCS and all but two coins were minted in Denver and SF.
Silver money was preferred in the western states to a much greater extent than the eastern ones. Possibly because the silver mining industry was located in the western USA.
I can't find the reference on short notice, but I read about it a couple of weeks back.

Carson City Nevada was the location of a US Mint facility. That's the CC on the bar in picrel.
