Microsoft Lumia 950
Unlocked

1. I'm not familiar with the "display dock" (what it is/does)... can you upload a photo of it, and one of it in use?

2. You are aware you are asking far more than this phone goes for on this platform typically? Like, 3x more? I understand it comes with the accessories, but is there something particularly special about this particular handset I'm missing (this is an earnest question, I've never used a Windows Phone in my life, but was looking maybe to buy one as a collectible.)

Hi Geoff,
1. Display dock info - https://www.microsoft.com/en-us/mobile/accessory/hd-500/specifications. Video about how it works - https://www.youtube.com/watch?v=4EhoVomaEOo
2. Personally the typical price on this platform is irrelevant to me. There is only one sold for ~75 USD. On Ebay the avg price for a used one seems to be about 100$. With the case, screen protector and box and a display dock I think it is worth atleast more then 100$.

Anyways if you are interested feel free to make an offer.
