Yes, the time will come, but now is not that time.
The magic-markered F -> M designation is possibly one of a kind, and along with the DOB makes this board VERY collectible. I would never offer this board up in a trade, either. If you want another board, buy one. If you want to pass this on to a collector, just sell it straight up. No one will have anything to trade with as much COLLECTIBLE value.
The earliest known Model M is a pretty cool thing to own.
