In a batch I’m going through. Thought It was funny when the entire batch jumped onto the magnet. Nothing I paid for so all good.
The types shown there are all types extremely common for cheap fakes. I see buckets full of them in every asian market I go to. I would never buy chinese, french, or british trade dollars or chinese fractional silver unless through a trusted dealer, (for anyone else reading this, I know you said you didn't pay for these OP).
There are some genuine foreign coins which are magnetic. I have not run into any of them for a while, since it's not my area of interest.
