Those auction results confirm what Vetech guessed for value, most auction results these days didn't actually sell, they were just fishing, and most would be in worse shape, so a value at the top of the auction results is reasonable. I agree with asking a fair price for it and not giving it away, it will get the most loving home that way, only half joking.
As far as the tractors, that Ford is clean and attractive in today's market, it's probably gained more value in the last few years than the Farmall has lost. Farmalls are now more collector tractors than hobby farm, and the value has dropped since ten or twenty years ago. Sorry, can't guess a value there.
