Chinese Silver Coin ID Help:crown, Tael, Fantasy?

I don't know how you manage to determine it's silver but if they are all magnetic, they cannot be silver.

I am 99.9999% certain that what you have are all counterfeits. Chances with one buying genuine Chinese crown size coins off the streets are worse than winning a lottery ticket.

Feel free to post photos of them but don't be devasted to hear the bad news.

You are in my particular area of interest here - I have been collecting counterfeit coins for over 50 years and have MANY thousands of them. A good friend (now deceased)once told me he hoped I never died because he did not want to think about my collection being sold. He thought it was that dangerous.

I can absolutely confirm the coins are forgeries (Modern and extremely common). The magnetic ones are often nickel - the "Other" magnetic metal. If so then they do have an intrinsic value. Some are struck in iron usually with minimal relief as you can imagine. These sell in Hong Kong in quantity at far under $1 each and one website promised it could deliver 250,000 copies a month at 10 cents each. I could never figure out why anyone would want a quarter of a million fake dollars but to each his own,

Have fun with them - they do sell for up to $1 each in the US and there are literally dozens of varieties. It is an inexpensive way to accumulate a lot of coins.

If you ever need a free second opinion on the authenticity of nearly any coin just post the photos or contact mne directly.
