Depends on the specs and the condition. Sounds like the physical condition is good -> very good... but what about the specs? (Memory, hard drive, processor, etc), and which version of OS X are you running / can you run? Does it run good? Heat up, etc? That all has to factor in.

A couple of places to check might be eBay (look for SOLD units, not FOR SALE, as a seller can ask anything, but SOLD will tell you what they got) and a recycler like Gazelle. Recyclers' prices will be low, but it might give you an idea about the bottom end of the value range.
