Very Cool (And Expensive!) 1809 Half Cent.

I spotted this Cohen 1 1809 half-cent in last week's Great Collections auction when the bid was $125. It ended up going for over $4800 (!!) . . . The Cohen 1 attribution is not called out on the slab, and not noted in the description, but obviously a number of us recognized what it was (

What I found interesting is that this exact coin sold for $6K a little over 2 years ago at Heritage:

Now, is it less expensive today because the attribution wasn't noted? Or is 1809 C1 low R4 now, with more examples being identified every year? (inferior examples have sold for over $10K in the past!!).

Old copper is so, so cool . . .
