Hello, I've recently come across quite a few Mac parts in a purchase, and while I've had a fair amount of luck locating them online, there is 1 item in the batch I have no idea what the value is due to the nature of its condition. The item is a mouse with the model number A2M2070, and it is in a sealed box, with the plastic still wrapped around it. I'm seeing these mice go from $20 to $40 approx. in working condition. However, I can't seem to find any hint as to what its value might be sealed in box. Any help would be awesome, and thank you very much in advance!
