Yep, it's a modern "Feng Shui" replica of a Chinese cash. Often used in making charms, wall hangings, "coin swords" and such, which are traditionally made up of "sets" of different emperors, or different provinces. Apparently, the evil spirits can't tell the difference between genuine coins and replicas and are equally repelled by both.
The genuine coins are so cheap and common, this is one of those cases where the value doesn't really change whether it's fake or genuine. Many coin dealers, around here at least, have a bowl of "Chinese cash coins - $2 each" or something like that. In the bowl you'll usually find a mixture of genuine coins and replicas.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
