Identification of an Asian (Chinese?) [gold-plated?] Year of the Horse coin 1990 [opgelost]

@ The Origin of this Asian (suspect Chinese?) [gold-plated?] Year of the Horse coin, 1990, has been eluding me since I bought it and I would like to know anything about it that anyone can tell me, as I would like to sell it and give more detail than the previous seller could give to me, which was close to nothing. Any help with any aspect would be greatly appreciated. I don't discount that it could be exonumia, but I have no idea. Possibly, it belongs to a set, but that is speculation on my part. I have run it through Numista's image search and Google's image search on more than one occasion. Identification is my main concern, an idea of value, would be a bonus.

 Thanks, AY

and Shenyang mint 1990 Lunar house 33mm China Coin Brass Medal  (I'm guessing they meant horse.)

And one more China Zodiac Medal Token Sealed, 1990 Horse

rsirian1 to the rescue, again! Thanks. Two things though, The previous seller described it as gold-plated, and it looks like other gold-plated coins I have, or is this a brass proof? Cheers, AY

I already told you more than I know.  😉

I didn't find any ebay listing of similar mint medals that mentioned gold plate so I'm guessing not.

I don't mind if it's gold-plated or brass, I only want the truth, and do you know, please, what the characters say?

Only the ones at the bottom:

Shenyang Mint

I'd say it's a brass proof. Thanks for all your help, rsirian1. I'll leave the topic open for a short while in case anyone has anything to add.

 All the best, AY
