For those of you that find a store like this, see the sale prices of items you owned as a kid, and remember how little you paid for those items in comparison, don't think you made a mistake by NOT keeping your old toys. I did, and it was the wrong choice.
I moved boxes of old 80s action figures and vehicles around from house to house, apartment to apartment, years in a paid storage space, only to later finally sell nearly everything at the "high sale prices". The amount of bother over the decades, amount of time needed to prep things for sale, find buyers, etc was a small fraction of a payoff compared to what I could have done with my time and money over the years.
If you made it to adulthood without all your old toys, you made the right choice.
Even worse- don't leave it for your kids to deal with.
My dad was sort of a hoarder, but for stuff that isn't totally worthless like just piling up garbage, but he bought stuff all the time because he thought it might be worth something someday. Like he bought three Big Mouth Billy Bass fish. He also collected LPs, CDs and DVDs. Mostly movie soundtracks, classical music and popular music for the 1920s and 1930s. All of that has value to the right person, but finding the right person is very difficult. I ended up selling off what I could of that, giving away what I could (most people didn't even want the CDs) and the rest ended up going to Goodwill.
He also collected stamps- first day covers. Hundreds and hundreds of them. I got about $400 for those. And stacks of sheet music, which he bought because he liked the covers (he couldn't play any instruments), which I couldn't sell.
I don't want to sound like it was all worthless. Some of the coins and jewelry did pretty well at auction. But dealing with it all was exhausting. I even tried the antique mall booth route for a little while and it didn't help much.
It depends, really.
I had an old comic book collection, kept in storage at my parents while i was overseas then my family hauled it around until we sold most of it downsizing to move overseas again (for the final time). Sold both copies of SW #1, but have #2 through 30 something.
At this point they were unboxed and put on display becaus they are neat and should be enjoyed.
Also found a bunch of old posters that are now framed properly and in our flat- everyone seems to really enjoy the nostalgia.
To be fair, the person you're replying to is saying it wasn't worth the hassle of hauling it around. You're saying someone else was hauling it around on your behalf.
