I keep these old ones too. I was looking back at them to see if I missed something and I did! Lamination error lol
I went through a hundred thousand plus coins when I was CRH and never found as many errors as you, have you bought your lottery ticket. (Lucky @Shrews1994 )LOL Dave
Interesting that Canadian coins mostly look the same today, even after 50 years. I think the Canadian cent is not produced anymore, though.
Lol no I haven't bought a lottery ticket I'm not lucky on those lol. I get many clashed dies the most I have over 100.
