.17,trapping is work.If you are looking for big money,get a job flipping burgers at Mc Donalds.
Coon prices vary from area to area ,depending on the coon you have.I will get $9.00 each for my coon(green,not put up).
Coon are a predator and need to be controlled,like all animals.
If you let go any you catch,you sure aren't helping your duck and Muskrat populations.Ypu can harvest your coon and utilize them,or mother nature will take care of them---and that ain't a pretty sight.
