No one is going to pay that. Either they don't know what it is worth, which means they don't have 50k, or they know what it's worth, which means they won't pay 50k.
No good reason not to pay $50k for a juju, if you have it. They're pretty rare (something like $20k might sell a bit faster tho). However, you may want to reconsider selling it at all. Have you double-checked that there are $50k homes for sale at this time?
