[QUOTE="manymore, post: 1220508, member: 17118"]As you might expect, experience in having seen thousands of real Chinese coins before is the best guide. However, I can point out a few of the more obvious differences. If you look at an authentic cast coin, like the one I link to above, the top surface of the Chinese characters tend to be broad and very "flat". Compare that to the characters on the machine-made coins which have a much thinner and much "rounder" appearance. You cannot achieve such fineness with a crude casting process. This same "roundness" can be seen on the inner rim around the square hole on the machine-made coins. A cast coin will not have such a perfectly square and uniform inner hole and it will usually have excess metal on the inside as well as file marks. The field between the characters on machine-made coins is also not natural. It has purposely been made to have a "bumpy" appearance to make it look more like the rough surface of a cast coin. Finally, Chinese cash coins are made of bronze. The reproduction coins are made of brass or some other more modern alloy. These are just a few simple guidelines. I hope you find them helpful.
