Jupiter 500 Series Alto Flute and Yamaha Piccolo

[dswen]

Hey, I have a Jupiter 500 series alto flute with a straight headjoint. I don't have the curved headjoint one. It is in pretty good condition. It has light scratches as with any used flute.
I have no idea when this was made. (Flute is fully functional)
How much do you think I could sell it for?

I also have a Yamaha 32 Piccolo.
Good condition, rarely played. No idea when it was made or purchased.
Any idea how much this is worth?
(my dad bought these flutes a long time ago. I play flute but not alto or piccolo. Piccolo hurts my ears and alto is not really suited for me as I have small hands.)

Thank you so much!
