The zodiac commemorative medallion of Shanghai Mint is a snake wrapped around a monster with tortoise shell.

I have one too. It seems to be gilded. It's a gift from the employees of the Pearl River Bank to my family. There should be less outflow. I just found two results online.

Shanghai Mint (Rare Coin Factory) 1988 Your Society (Xuanwu). Beishou. Copper coin auction 10-80 yuan. But I think people who know this currency release less information, and it is within the bank. So the circulation should be small. Coins with face value are also used for collection. This comparison with no face value is memorable. Therefore, there is still some room for the collection to rise. I don't know if it was put on sale in the past. In addition, I also subscribed to Xuanwu commemorative coins on three websites. Value negotiation. And this is an online auction price, not an antique shop auction price. If you really don't like it, make a fair price that is suitable for both parties. Give it to me! !
