Silver is at 20.10 an ounce

The Silver eagle market is around 22$ for a regular date - so thats the bear minimum.

All silver eagles are uncirculated so quality is prob not an issue for you, if they are still in their original case from the mint they are probably ms 67- to ms 69.

Both of your coins are around $34-40.

Hold onto them, silver will probably increase even more as the economy slumps.
