·We're pretty certain on the serial number range. All were produced in the second half of 1970 (and from extracts it seems most were October). The currently accepted range is between 30,588,xxx and 31,008,xxx but some seem to have it tightened down further to two blocks of numbers within that range.
This is also the reason that the bezel itself doesn't really carry a premium. You can't take a 220 bezel and put it on any 145-022-69 and have a "220 Speedmaster". You could put a DON, 220 or DNN on a watch in that range and have it "correct" but not the other way around. That said, I am sure the 220 Speedmaster already has a premium over a DNN Speedmaster though it's priced less than a DON Speedy. Where the price differences will go is anyone's guess but spotting the difference will be tough because of the limited number of them that go for sale and the fact that @Barking mad and @Foo2rama own most of the true examples between them.
I have a good example of a ghosted 220 that's sitting on a gorgeous 1039. Now, if we go by speedmaster101's current price chart, that watch is going to be £4k and the bracelet £1.5k ... yet I can tell you for a fact that it's never going to come off my wrist for that sort of money.
Thanks for the info. I'm actually in the process of buying a 220 Speedmaster (145.022-69) with serial number 30,996,xxx and pre-moon case back. I'll post pictures here when i get it (within a month). It sits on a 1035 - which is not correct for this reference if I'm not mistaken. But perhaps valuable by it self.
