I bought a lot of flutes on ebay (4 together in one buy). I just bought them to take apart, clean and fix minor things, and see if I can make them be nice again and play

Anyways, one of the flutes was a beautiful Gemeinhardt, open hole, straight line. It was a bit dirty and when I took it up, I noticed awful dings in it (I knew there would be some body damage, said so in the description) and it just broke my heart to look at those dings. So I put it aside for later. Just recently I opened it up again and decided to polish it a bit and see if I could get those dings out (just gentle tapping). Sooo...
Now I can see that just under the place where headjoint and body join (where it says what brand the flute is) it says (almost not noticable) SOLID SILVER. Does that mean that the headjoint is solid, or the whole flute?
Now I've started to think about asking a professional to get those dings out and use it myself. What would you do?
TL;DR: What does Solid silver really mean? What would you do with a dingy flute?
(P.S. the dings were like someone slashed the flute against a table corner several times.. there are about 7 dings on the body and 3-4 on the lip plate)
