I have a chance to trade my Haynes Vintage 1922 Plateau Flute for a Rare Artley Ogilvie Bass Flute and so he says its from the 70's in great shape. My question is this bsss flute worth 6000 ? Or should I pass and keep mine which is valued at about 3000.

If it's a clear trade, pick the one that you play best.
Which one do you make the best sound on? That's the one you want regarless of alledged value.
