I have 31 marten to sell this Saturday in Montana. I have one which is ragged and flea bitten and looks terrible the rest are great. Do I put it with the rest or sell it separately?
Also is there any advantage to sorting my marten by size into different lots or will thy all get mixed up anyway?
My goal is maximum total price, I don’t care about my average particularly. Thanks!

I don't trap marten but I'd sort them out even if you did it after you get to Livingston .

The poor fured marten will bring down you're average , id ask Guy or Bob when you get there maybe they can give you better advice .
The advice I'll give you now is I'd post this to the Montana Trappers Chat you'd have a better chance of getting quicker response than here on a strict trapping only chat .

Maximum total price = your average.

A bad pelt is gonna bring down your average whether it’s in a lot of better stuff or by itself.

If it’s that bad, maybe keep it. Tan it or something.

Personally, I don’t pull one or two bad pelts out of a larger lot (except maybe cats).

Use the good fur to move the bad fur.

The bad fur by itself may not sell at all, than your stuck with it anyway.

I figure there are always crafters that may want to work with a less expensive or damaged pelt, and separate them out for those people.

I’ll ask when I get there and likely sell it separately. Thank you!
