Ancient Chinese "Da Quan Wu Bai" Authenticity Opinions

This is a fairly rare coin from the Wu Dynasty. Some severe inflation was occurring at the time, and this coin reflects the inflated nature of the coinage of the time. The translation of the coin's inscription is "Great Coin Value 500," which gives this coin a denomination of 500 Zhu, which is about 50 times its metal value.

These were cast under the founder of the Wu Dynasty, Emperor Da Huang, in 236 AD. The high value is likely because the state needed a way to pay its soldiers during this very turbulent time (the Three Kingdoms Period) of China's history.

Another interesting factoid: due to the highly-inflated coinage of the Wu kingdom, counterfeiting was rampant and very profitable. To counter this, the rulers of the Wu ordered the populus to turn in any bronze ware they had in order to deprive them of materials for counterfeiting.

I paid just a bit under $25.00 for it, which I believe is a good price. These are fairly rare which is why I have some concern. I feel it is genuine, but I'll let those more familiar with what real patina looks like give their opinions. Size is 29.2mm, which is about right.
