Here is a nice early U.S. Mint set, in 3 cardboard holders and envelope.  I believe this to be an original set, and not picked over or coins replaces, as they all seem to match pretty good on the toning and original surfaces 'skin' of the coins.  There are various amounts of toning on the coins, I have not been able to capture it very well on the photos.

This is a double mint set, where they provided 2 coins for each mint and denomination; so they could display both the front and the back on each holder.  Thus, there are two 1949-D half dollars, quarters, etc.  Likewise for the Philadelphia coins, and the Denver coins.

Looks like some nice coins; perhaps some full bell lines, etc.  I have not removed any coins, as the back side paper flap is glued down, and I do not want to risk damaging the holders.  So use your judgement.  Also, I consider the value of this set is due to the originality and matched coins in it, so if any coins are removed by the buyer, I consider this to be non-returnable due to potential damage to the holders and coins.  So please keep this in mind if interested in this set.  These old sets are hard to find that have not been tampered with.

BU Uncirculated, original set, with 3 cardboard holders and envelope; no mailing envelope.  The envelope has an old price on it and some other writing.  This will make a  nice addition to your collection.  S/H $35.00; I do combine shipping on multiple auctions won for a savings to you on shipping.
