longnine009 I missed your comment about the small curl. Not only can modern transfer processes pick up features that small - they can pick up features much MUCH smaller.

There are several different ways to make dies and molds from real coins. Gone are the days of lead castings in plaster molds. Some of the current techniques are easily spotted others are not, but the use of dental plastic can and does produce very small features - some of which are only visible under magnification. This development which is the origin of many of the Chinese fakes has made die forgery rather easy and inexpensive. Even though the dies only last for a few strikes, they can be made cheaply and QUICKLY. That is one reason why the fakes are proliferating so darned fast. They can buy a coin and make a copy within an hour or two. That is also why some of the Beijing forgers are actually taking orders for specific coins.
The world of counterfeits is complex but VERY INTERESTING. I have been following this side of the hobby for nearly 50 years now (since 1960) and there are new things I am learning (or re-learning) daily. One thing I have recently learned is that short term memory is the first thing to go.
