I'm going to go a little out of the box here with my comments. Not meant to offend, just my opinion. Any item, including FW's, are only worth what someone is willing to pay for them. And that's when you sell them. If you're looking for an insurance rider then you will have to have an independent appraisal done just as in for jewelry. If you're looking to purchase, than the 'value' should be predicated on your budget. I don't believe in paying an exhorbitant amount for anything just for the purpose of owning it. Granted, I was very fortunate to get my FW, in excellent condition, for $25. And even though I'd wanted one for quite a while for a host of reasons was not willing to pay a great deal of money for one.
