Help ID cash coin China

Hey I bought this giant cash coin looks to be the size of a US half dollar 30mm plus. Would love some help on the identification.

正德通寶

The Zhengde Emperor reigned from 1505–1521. 

However no circulating coins were produced during his reign. 

Coins bearing his era name are minted from late Ming to early Qing, with modern reproductions (Usuelly found at Taobao)

They are lucky charms, with auspicious depictions on the back.

平太 : condensed form of 天下 平太 (tiān xià tài ping = "peace under heaven")

You might include your charm in the Exonumia section
