An authentic USA stamp: MNH REGUMMED US Scott # E13 Special Delivery 1925, 15 cents CV $75.00 Rare! Catalogue valued at $75 USD, letting go at $40 SGD as I wish to let go my stamp collection. I had stopped collecting stamps for more then 15 years now hence I sell cheap, another reason is because stamps are difficult to sell at a good market price. For a long time, I am an ancient coin collector and will be as one till the day I die. Lol. Authenticity guaranteed! Full refund if fake!
