Price Advice Family member just picked up an old Mac, need some guidance

[nomosolo]

Hey everyone! Some family called me yesterday saying she picked up an old Macintosh at an estate sale for $200. The owner said it was bought when they first came out in 1984 and was a 128K. It was upgraded by Apple in 1986 to 1MB and has the "Macintosh Plus 1MB" on the back, but is still just an upgraded original 128k.

HERE are some pics of what she got.

My question is: what do we do with it? She owns an antique store so she could definitely sell it, but for how much? Apparently everything works and boots up (well, with the "?" flashing haha). Thanks everyone for any feedback, I'm a bit lost here.

Not worth much. Most collectors want a true 128 not a plus upgrade. If it had the original back and board with it that would be something. At 200 bucks you probably paid the premium price for it.
