What is your observations about the reverse of the 'Hot Springs' quarter??
The "field" of that design will always look a little rough. This is
because it is supposed to show the facade of a building (see
http://www.usmint.gov/mint_programs/atb/?local=HotSprings ).
I too am on my second return. This replacement is "backordered." I had to
return my first Unc. set because of brown "splashes" on the NA Dollar coin.
