I agree that it could go for just around $50 but only to someone with a strong interest in developing it. If this was YourPhone I'd say it would have a lot more value and as a .org it isn't a very strong name. Google gives over 40 million results for "your phone" only 2 million for "you phone" so the keyword combination is much less valuable.
This would be a good name to build a mini-site on and monetize. If you can get some organic traffic from search engines you might be able to make some money with the name. You can then sell it with traffic and revenue which could get you over $500 for the name...but that all takes time.
