Help Identifying Chinese Coin

While not a match to your coin, perhaps the link to these two coins on Heritage can provide a stepping stone toward the identity of your coin.

China: Kwangtung. Kuang-hsü Fantasy Longevity Tael ND

China: Kwangtung. Kuang-hsü Fantasy 1/2 Tael

The coin in the original post and the eBay auction are both modern counterfeits from China and are of no value.

The Heritage coins are both genuine.

So I would say, if you want to turn this into a positive, figure out what the Chinese characters are for the dates, etc. Also, compare it the originals to get a sense of toning and calligraphy; those are usually the two items that first tip me off. Beyond that, it would make a cool necklace or pocket piece!
I have several Japanese fantasy pieces and Chinese charms in my collection. There seemed to be more of a market for them in the first heyday of Chinese coin collecting. I think most of the reference guides are outdated/out-of-print. They are too easy to fake, so the ones that seem to sell are ones with a provenance in a well-known, older collection.
