Also marked it with a pencil to remember what was in the box. Please look at the photos. I opened one set as an example to show the coins, and had looked at every set long ago and can not remember if there were any of the doubled half dollars or if there were any stand out Cameo co ins either. I don't want to know either, I had these tucked away in an ammo box for so long and remember the hassle of looking through 50 sets. I do remember having to carefully open a lot of the envelopes some may have resealed since then?The item "1961 US Proof coin set SILVER Half Quarter Dime Original box of 50" is in sale since Wednesday, April 06, 2016.
