I love them. i may even go so far to say that prefer them to silver toners. i have seen a lot of late 70's and early 80's tone up really nicely.
You asked for it Riff! I also like clad toners. They are a lot harder to come by than silver toners for sure. I'll start off with a few.
i will break my own rule and show a couple business strikes nickels for gbroke. i kept them to see where they go.kind of hard through the cellophane because of glare.
Here's one: Notice the rich gold undertones along with the light lavendars and blues. It'll definitely be a keeper "when" this occurs in 50 or so years.
Absolutely beautifully-toned specimens! It looks a new group of what I like to call wild purple nickels will be joining the electric blue dime of the OP and all of the lovely sunset quarters, halves and dollars!
