The 1953 nickel looks like the No Shoulder Fold (NSF) and Far Leaf variety to me. Assuming the coin is in AU grade (to be conservative), this coin retails for $8.00; however, what a collector would be willing to pay for it in today's market is another story.
The 1948 nickel probably grades VF or so, and retails for $5.00, as was previously stated.
