Hello Just4fun,
All three of your
Liberty nickels are low-grade, common-date coins and have correspondingly low values. I would estimate their values at only about $1 each.
The 1910 is the best of the three and grades around Good-6. The 1904 is maybe G-4 and the 1907 is a very tired AG-3 at best. All three have been cleaned as indicated by the fine, curving scratches which are visible mostly on the obverse. The 1904 also has some deeper scratches.
These coins are perfectly OK for a low-grade
Liberty nickel set. I would use them to fill the holes in the album and replace them with nicer coins when you have the chance.
Good luck!
