1834-D Germany/Prussia 4 Pfenninge  - Friedrich Wilhelm III .  This copper coin has a weight of 6.15 grams and a diameter of 25.4 mm.  The obverse is the crowned Prussia crest with "90 Einen Thaler" surrounding.  The reverse has the value and date with "SCHEIDE MUNZE" at the top.  The rim has raised circles.  This coin was minted in Dusseldorf, Germany.  I would rate this coin in either almost good or good condition with a clear date and lettering, but definitely worn.  Nice one to add to the collection as these just aren't out there.  Take a look at the photos and thanks for looking.
