I think a few years ago they were considered fairly rare, but as more and more of them show up, their rarity isn't as pronounced. I recently found one while searching through Canadian rolls of pennies, so go figure.
I found 10-15 of them searching OBW rolls of 2000 cents, back IN 2001. They were calling it the "type II" reverse at that time. of all the Not intended wide AM's, 2000 is the most common. I still hang onto them. always worth more than face value.
