Any "W" enders? I'd open some and then sell the rest. I have a box coming tomorrow and that's what I'm going to do. They are HARD to find. Mintage will probably be 350 million quarters w 2 million "W" thrown in. So what's that...1 "W" for every 150 regular quarters?
They could all be regular issues. Whole rolls are in the $25 or so range on ebay. It's been frustrating. I did however find a Kansas quarter with the error "In God We Rust". Grease filled die. It's a $20 piece. I sold all my extras, about 10, and the rest I am having slabbed by PCGS. You're lucky to get a complete box.
The value of the W's keeps dropping, so that alone would convince me to open them up. If you try to sell rolls, the price will drop more and more and then if you open them, it will be too late to sell the W's alone for much either.
Different when there is something with a fixed value, but look at how the First two W's have traded, and that will tell you what to expect.
Don't expect to find a solid W roll, or even an ender. The W coins were to be inter-mixed within the regular commerce production output coins of the P&D, then bagged or boxed.
