Some old science and medical devices or tools can do really well, especially when you go back to the turn of the century. I was a bit surprised this was worth what it sold for but that's why I know to research unusual things and have both books and internet resources to do so.
I love old lamps and lighting. Really good old stuff like this can be worth thousands in good condition. These were incomplete and had some damage but even still, they did okay.
These took a surprisingly long time to sell considering how cool they were - at least I thought so. Period textiles and decorations don't usually hold up so I can get pretty good money when I find them in nice condition.
I just love selling random vintage stuff like this - these would be worthless to anyone without taking the effort to sell them on eBay but that's what I do so I did it....
I over-paid for a bunch of premium vintage toys year before last and have been fishing to sell them for top dollar just to make my money back. This sold for a good price but it took like 16 months to get it
Another piece sorted by our senior volunteer Phoebe - nice job - we never would have gotten this price in the showroom
Before Ikea, there was Scan, and the put-together 'Danish Modern' furniture they sold was actually real wood and nice quality at that and it's in style again and can sell for stupid money.
Some vintage items are so 'who would even buy this' that I just know they will sell.
Some vintage toys can be extra special due to a certain paint color or decal set that was less common - and of course condition is everything.
I had one of these a couple years ago and made the mistake of selling it outright for $200. Knowing that some vintage advertising promo stuff can sell for big money, I should have auctioned it on eBay like I did this one.
