Let me have a go at the question of value.
Is a '63 split window Corvette that has a stuck motor worth more than one that runs and drives?
Would an Invincible that cannot be shot worth more than one that can be shot?
This is not meant to be unfriendly. Just a lead in to my thinking of rarity on the market place.
If there be a one of a kind item, there is no reasonable way to determine its REAL value. The are no comparisons to judge by.Easy to determine worth if two deep pocket guys wish to fill a collection hole. False value. Perhaps a valid worth.
Worth is not synonymous with value. Think about it. Being worthy is not the same as having value. That hair must be split when thinking of adding any material item. Should also be considered when voicing opinions.:}
Oh Well. You long time members know me by now. Turn those horses loose !!!!LOL
Best,
