Can anyone explain this. When a collector finds a prototype for sale exactly what is it he should do? This is starting to sound like "the pearl" and collectors should throw them into the sea and avoid all of this.

If he buys it for asking price then he is taking advantage of the seller.
Yet if he believes the prototype is worth more then he is inflating the price.

If he sells a prototype for going rate he again is inflating the price for gain.
Yet if he sells for less than going rate he has been caught in his lie about the price.

If he keeps the prototype it to himself he is a selfish horder.
Yet if he instead dumps the ROM for all to share he is illegally making copies.

There is no prototype collector in the world who can escape wrong doing by these guidelines. Everyone of them has either dumped or not dumped. They have all paid asking price at one time or another when items are posted for sale. If asked for a value they have all quoted prices on items above what someone may have once paid.
