Gilbert MainesI will place my vote.
To me, a restored card is almost always worth less than an unrestored one. But I recognize that others may feel differently. Therefore, I support the existence of card restorers.
The above opinion is not universally applicable. That is, a shattered vase is worth more restored than a pile of rubble. An antique auto is worth more if it is in running condition; and when faced with a charging bear, Id like to have my gun in working condition rather than all original.
Similarly, if the item is unique, there is no comparison. Therefore, a card of which a single example exists can not be hurt in value by its condition, in my opinion. If the custodian of this unique historical object chooses to clean it or otherwise alter it, this action has no negative effect on its value, and may actually improve it. In this case I consider the card not unlike any other art object.
