I would say that it is worth about $75.00, since that is what you paid for it.
Bows are worth what someone will pay...no more, no less.
I just picked up a 45# 52" Ben Pearson BPH52 off e8ay for $45.00 in about the same condition. Expected that it would go higher than that but was surprised to learn that I had won it.
Part of this depends on what they buyer wants. Personally, I would consider a browning to be worth more than a Peasron, but then that wil lvary with the individual.
If it is worth $75.00 to you, then ya done good.
