Any one into error collecting is going to know that it is impossible to get two headed with differing dates.
Well.. just because someone is into error coins doesn't mean they know a whole lot. There are a LOT of un-edumacated collectors out there. They like certain things, but haven't taken the time to educate themselves on what certain things are, how they are created, etc.
There's always a period of time between when a person starts collecting and when they start
learning about collecting. It's within that time where they are most vulnerable - and it's exactly that time-frame that sellers like this are targeting.
If that buyer had done one search on google on a double-headed coin, they would have seen 85 results from this forum alone (ok, only a slight exaggeration) and would have been pre-warned. Simply, some just don't do their research until it is too late.
