How much should I ask for my used equipment?

Been a decent sized hobby beekeeper for the better part of the last 10 years, but life is getting too hectic and I'm not tending the bees like I should.

I have a beekeeping friend who is interested in buying out my hobby. I will sell 10 frame deeps and honey supers, all wood frames with plasticell and drawn comb. Minimal wax moths damage. Latex painted, weathered well, no rot or issues.

What should I ask for this? I was thinking half of what the bee store sells for. Just looking for a fair deal.
