Use a bonded and insured numismatist. Photograph everything front and back before you hand the stuff over, and get an itemized appraisal. That "04 Morgan is surely worth more than the $60.

Understand... I'm the coin metal guy, not the coin rarity guy. That selfsame nice '04, to me is approximately 26 & 2/3 grams of 900 fine silver (900 fine is 90% silver. Sterling is generally 92.5%, or 925 fine. The present American Eagles minted out as West Point are 999 fine, and the Canadian Maple Leaf is 9999 fine, respectively 99.9% and 99.99% pure silver.). in short, I'm the barbarian who finds the value in the smelting ladle, not the Danson collector's album or Gray Book.
