Talk:Chinese wen
From Wikipedia, the free encyclopedia
I read on a Chinese webpage regarding the square holes on the Chinese coins. The question was that if the hole is solely for threading the coins together, then why was it square? The theory was that the minting process back them was not very sophisticated and the minted coin usually have rough edges. A stack of coins would be stacked together and held still by a square rod through the square holes and the blacksmith would file the coin smooth as a group. I just read it from an article and the article didn't quote any source, so believe it or not! Kowloonese 00:35, 9 February 2006 (UTC)
