Have some questions about 3 coins [opgelost]

The 2006 and 2007 Turkish coins seem to have extra metal all around the reverse is this normal?


Also the 1977 Canadian 5 Cent is this acid dipped?



Thanks for any help. Also sorry for the scans cheap scanner.

The 5 cents doesn't look dipped to me. No idea about the other two.

"The 2006 and 2007 Turkish coins seem to have extra metal all around the reverse"

If you mean around the very outside edge of the reverse, my 2005 has the same around approx 60% of the circumference.

Thanks guys much appreciated

Errors on Turkish coins of that Era are very common. Almost all of them have similar malformations.

The Canadian nickel is just corrode. Nickel turns black the longer it is buried.

​agree. I have plenty of them, and all of them have something, making each coin unique :)  :)
