Congrats on the find and I for one, hope that it is real! The overall color of the coin, the Copper looking color around the edge of the rims as well as inter-mingled on some of the details/images and although the coin shows very little signs of wear, the lack of details on Miss Liberty's gown and the Shield, leads me to believe that it may be an older Counterfeit. You should weigh the coin and compare it to the normal weight of a Seated Liberty Silver Dollar, do the ring test, examine the areas mentioned for Copper underneath a Silver plating job and if still uncertain, take the coin to a knowledgeable and respected Coin Dealer to have it checked.
