I have reached a point in life where I don't deal with money on archery things or other stuff I don't use and don't need. I usually get together all my excess archery/hunting stuff and donate it to the Trad Gang St Jude Auction every year.
I do sell a lot of closet clean out stuff on the Facebook Market place but I price stuff at a giveaway price. I get swamped with buyers at these prices, If I offered the items for free I am sure the sharks out there would pick up the items and would quickly resell them. I do offer what I consider junk items for free, I could probably get a little money for these items but I just want some one to carry them off, in 100% of these junk item listings someone will pick them up.
Sometimes I can transfer an item to someone who really needs it and it makes me feel good in a way that a few dollars in my pocket wouldn't.
I found a brand new fold up roll away twin bed in my late wife's closet, I looked up it's value and found it to be $125, I put it on the marketplace for $10. A lady contacted me but her husband missed the pickup information and didn't meet me. Ordinarily I would go on down the list, the lady apologized and offered me more money if I would give her another chance, I told her a deal was a deal and $10 it was, she made sure her husband made the pick-up the next time. After the sale the lady contacted me and said she had a grandchild that stayed with her but he had to sleep on the floor because they couldn't afford a bed for him.
On the wheel bow you have a lot of options, when I was your age it would have been sold in a heartbeat and I would buy trad gear with the proceeds. I did exactly this with my decked out almost new wheel bow in 89 when I went back to my traditional roots never to leave again.
A charity donation is an option but that option is more for us old guys who have enough "stuff" and don't want any more.
I have been at a lot of trad tournaments where someone would win a raffle prize bow, turnaround and start an auction for the bow and donate the auction proceeds to the clubs charity which in our case was the Alabama Children's Hospital. Now that kind of gesture warmed everyone in the crowds heart.
