I have always noticed that coins from the Denver mint are of a better quality than those minted at Philadelphia. In fact, I can usually see a Denver coin without even looking at the Mint Mark. Why is this so?
It probably depends on the year/coin series/production run, etc. I have not noticed a big difference in overall quality between P's and D's, although those San Francisco (S) minted proofs sure are nice. :whistle: TC
I finally stopped ordering the Proof Sets. There always was a problem with 1 or more of the coins. I often got stains on the gold Dollar and nicks on the Half. There were problems with the Silver Quarters all the time so I had to return for replacement. Often, the replacements were just as bad but the defects were on different coins. Once the package was even cracked!
I'm not sure which denomination(s) you are referring to, but for Lincoln Cents the opposite was the case for the Wheat reverse and earlier copper Memorial reverses. With these coins the branches turned out some poor quality coins as far as details and strike goes.
It's easy to state generalities but I find the opposite to be true in my part of the country. Perhaps you are a numismatic savant of some kind.
For post 1964 clad quarters up until the 90's the Denver quality certainly exceeded that of Philly. A nice Philly coin is many many times harder to locate in this series during these years. This is a fact.
