Nearly Complete Silver Washington Quarter Set- How Much Would You Pay?

Without seeing them in person I would offer melt for the silver, face for the clad, maybe 15 for the book. I would be prepared to add an extra 5 or 10 if the Bicentennials are indeed silver.

That should leave you some room to negotiate for any particularly nice specimens you find in the set.

As usual, take precautions!

There are more condition scarcities than date scarcities within the Washingtons.

You have the 34D and 36D so off to a good start there, you can find lower grade circulated 32S & 32D for well under $100.

I agree with Half and KenKat's pricing but maybe melt + 10% on the 36D & 34D as those dates get a premium even in low grades. Anything less than AU (prior to 1940) and less than MS (after 1940) is not worth much over melt. If any of the 1940 and later are in MS, $4 to $10 per coin is acceptable. The clad is worth face even in Unc. unless you think a coin is MS66 or better (prior to 1984) or MS67 or better (after 1984.)

Like Jefferson nickels, Washington quarters are a series that is very affordable in circulated grades, but offers great challenges for collectors pursuing high end coins; both series are full of condition scarcities in MS65-MS66 and higher grades / FS for Jeffersons. (Compare the price of a 1932-1964 Washington full set in Avg. Circ. vs one in MS66 and you'll see what I mean...)
