I am just starting down the road to world coins and a novice with regards to nuances in foreign coins. That being said. It is fairly common for foreign coins around the 1900s through 1950s to have incorrect orientation and significate degree rotation from Obv to Rev., on major country coins such as Russia, Germany France.....etc I realize that quality control may not have been paramount in those countries at the time. I just simply have not looked at enough to have an opinion on it. Thanks in advance
Interesting question. Not sure (particularly considering recent US Mint products) why we should doubt quality control for other countries. I'm sure someone here can help you out.
Yes lol, the US mint has not been particularly good about it either. Philly mint comes to mind on several occasions
The only advantage the US Mint would have over foreign Mints is long experience in minting huge quantities of a given issue. Even with attention to detail being similar - an arguable point in the cases of many World issues - the refinement of technique necessary to be able to continuously mint multiple issues in the tens of millions every year would force a less error-prone technique to be able to do it at all. You'll also note that many World issues have examples of major doubling which would be a "killer variety" in a US coin, like the 1955 Doubled Die Lincoln. You're seeing these countries go through the same learning curve the US Mint was forced to a century earlier.
