Most toys that are "new" are no big thing right now, if you want to make money on toy collections, it has to be older then 1974, this is the year where most toy companies went over to plastic, yeah some made tin toys for a few years after 1974, but then outsourced it to Taiwan or Hong Kong, the value on those are next to nothing. In the earliy 80's it was motly made in China. Made in China is bad for anything worth collecting.
I try to stay away from toys in general, but if i do come across toys like beanie babies or other collectibles, then i try to find a byer that i know collect it or know someone who does. With my beanie babies, i had to go thru 3 people to get a buyer. My point is, people use Ebay as the only place to sell or have a value set. This is so far from the real world as you can come. Ebay is a place to dump everything you don't want, becasue on ebay you have 80% low end buyers.
Let me take another example, fine china. Rulesforrebels said he could not sell it, well i can't sell that either on ebay, unless it is one piece someone needs to replace in their set, because their broke. I take my china to stores that sell china, both new and used. They don't buy it from me, but they are marketing it for me to customers that stops buy. And 8 out of 10 times i sell it. Then the store gets 20% commission of the sale.
It is all about creating a network, create relations with people, and then "key people" It is all in what i call creative selling.
But of course, if all you hope for is for ebay and craigslist to do the job, then you have limited your self as much as you can.
Places i try to stay away from when it comes to selling is Ebay, craigslist and pawn stores. These 3 places will not generate any profit at all.
So is there stuff i can't sell? of course, but i try to stay away from lockers that has that in them. Like mattresses, i hate them and i can't sell it. Another thing is books, i hate books, becasue i only get like 25 cents for them no matter what, and sometimes they don' buy it all, becasue it is not the right title. The 3rd thing i can not seem to sell is CD's and DVD's, So basicly i am building up my own CD and DVD collection.
