172028603543Reverse, right wheat stock. Unlisted? Looks like 1943S #21 I think it was on cuds-on-coins but I don't think it is. Looks like it starts at about 2 o clock, meets one of the wheat leaves and leaves a blob there, then branches out at about 4-5 o'clock. You have to use the
ebay image zoom to see the second crack.
$5 is too much without confirmation, though.
