Whats a T/C Contender with 5 barrels,221FB,357 mag,.45-410,22mag,22lr, 3 Bushnell scopes worth? In very good condition.

I knew a guy years ago that bought a similar combo, 22lr, 222. 44 mag. I think he paid 500 dollars about 20 years ago. There might have been another barrel too but I can't recall.

Stainless, or blued? G1 or G2 frame? Barrel lengths and profiles? Stocks?

There's a LOT left unsaid in the OP's question that plays into the answer.

Blued,10" Octagon's 3 standard fore arms, serial# 22xxx.
I would think G1's

All those barrels are blued, 10" octagonals? If so, figure $750+, just in the barrels. Frame is another $300+ for that vintage. Add in the stocks and scopes, and $1350-1500 is a fair decent ballpark for the whole enchilada; assuming you can find a buyer for all of it. If you are buying, well...

You generally take a hit when selling a package deal as the buyer will likely be interested in a few of the barrels but likely not all. The bushnell scopes aren't going to add much vallue to the collection. I think real world is $1000-1200.

All 5 of the Barrels are Octagon.

What 458 Lott said. Real world price between $1000 and possibly a bit more. It used to be the silhouette shooters that snapped up contenders... Now that sport is just about dead. The 45/410 barrel may bring a bit more than the others.

Octagon barrels are usually not sought after as shooters but garner a stronger following by collectors. Of the chamber mentioned the 221 Fireball is probably the most novel, then the .22 WMR and the other three are relatively common. Condition is everything when premiums are expected.
All and all barrels might average $175 each, frame and furniture will go for $300. If it's a square grip with metal plate grip cap it'll bring a higher value.
Hope I've been helpful.

Following this thread as I've a similar (different caliber ) package I'm thinkin of letting go.

I may let mine go as well !!!
