There's been a large number of books of Chinese dollar types for sale lately - listed as "80 Chinese silver gilt coins" or "Lot of 80 Qing Dy Surface Coated Silver Coin Collection" or said to be silver... these sets are basically pot metal coins - they are MAGNETIC FAKES. In fact 99% of the sellers based in china are selling FAKE GOODS. Avoid them at all costs, and let others know about the issue.
