spare Colt Trooper .22 LR 8" barrel price?

[WWGunslinger]

I bought I Colt Trooper .22 with 6" barrel awhile back and got a separate blued 8" unfired barrel with it.

I was thinking of replacing the 6" barrel with the 8" barrel but i think that would lower the value of the revolver as it is not it's original config?

Now thinking of selling the spare barrel as I could use some extra money.

What is the spare 8" barrel worth? I see some nickel barrels on gunbroker for between $70 and $90 but doesn't seem to show any that have actually sold.
