I really like the obverse of the reeded edge bust halves. Here are 3 from my collection, hope you enjoy them!
Some real beauties Doc . I have a lone '37 example . It is cool looking at all the different Miss Liberties used for the Bust half series , from the open collared 1807 to the '39-O like yours .
Rusty, that is a beautiful half! My 39-O came from CRO, I spotted it at their table at Balto. about 4 yrs ago and whipped out the checkbook. I agree that the blue green toning is unusual but it is quite attractive in hand. I have no idea what conditions would cause that color. To me, these RE busts look more "stately" than their predecessors (which are fine designs in their own right).
Well if you get tired of the '39-O , I'm sure a trade could be worked out . I bet she's an awesome colored coin in hand .
