1. Historically, the most often mint represented was usually the Philadelphia Mint followed by the Denver mint and then San Fransisco (not talking about proof or mint sets) along with the other mints (Carson City, Charlotte, New Oleans. What determined how many coins from each mint is made? Why didn't they just spread out the coins evenly? 2. I also heard that the mint makes all coins in one location nowadays. Is this true?
There were several things that came into play - orders from the banks was a biggie, closest mint would do the work. And if one mint was busy making this or that, then one of the other mints made something else. Uhhhhh no. SF does the Proofs. Denver & Philly still make 'em every year. West Point does the bullion.
Thats what I thought about the mints. I thought I saw a thread on here that said otherwise. I thought it was wrong. Maybe they were trying to explain the D/S mintmarks.
Another reason is the population distrbution. Although there are a lot of people in California, the bulk of the countries population still lives in the states along the eastern seaboard. So most of the coins are struck in Philadelphia so shipping is closer.
