identify7I believe that each error and each variation stands on its own merit. As such, the desireability of different examples will vary over time, based on collector interest. For example, currently cards which exhibit ghost images are quite popular. Additionally, some error cards have demanded high prices for decades. Similarly, as awareness of the variations which exist in many issues increase, and as information becomes available regarding the rarity and commonness of these cards, collector interest will certainly follow.
A recent poster asked about the value of a w516-1 Ruth card which exhibited an offset in the coloring. Some collectors expressed no interest, while other posters speculated that prices higher than cards with non-offset printing would be realized. I would not pay a premium for this error, but it is currently on eBay; we will see.
