DHP on 1937, 38 and 45 Dollars

[b1gb0b57]

Hi Guys!

I just got my shiny new 2020 Charlton catalog, so I'm fixing up my collection. and I ran across 'DHP' and 'QHP' listings in early dollars. This stands for doubled (or quadrupled) HP, designer's initials under George's bust. Can anybody tell me WHY just the initials were doubled and How (as re engraved, repunched, tooled, etc.)?

Thanks!

Bob

Found a 1947 THP

This was done in the mint, so there's no question of tooling. Can't think of a scenario that would cause this. It looks most like a mechanical error when the punch was applied to the die, as there was no attempt to hide or polish away the underlying punchmark. Bizarroïde.
