[QUOTE="HBrider, post: 2861959, member: 88009"]Out of the 100, 12 of them stick to my jewelers magnet. Probably about 4 of them, its a low magnetic attraction where the coin will follow the magnet across the surface. The rest, its a strong attraction where the coin will jump up and attach to the magnet when it is a quarter of an inch away. From what I researched, some bronze coins were mixed with iron (which probably got some heads chopped off), but I believe this is uncommon, and I shouldnt get 12 in a batch of 100, and maybe not ones that are VERY magnetic. I also suspect that this batch of coins were previously cleaned enough to be assessed and identified, and then were "re-dirtied" so they could be sold. It only took a very brief soak in tap water and a rinse, and much of the coins details could be seen, and the coins identified. Though I could be wrong on this. Perhaps the finders of these hoards don't even bother trying to ID bronze coins. Here's the entire batch, with the coins on the bottom being the magnetic ones...
