Make sure you want to sell them
The first step to selling your rare and valuable figures, is to question your sanity and figure out if you actually want to sell the figures.
Sometimes people tend to make impulse decisions, as they feel the need to part ways with their valuable items. However, with the matter at hand being worth a lot of money, you need to make sure that you are a hundred percent certain you want to sell them before you actually do.
Display items online or at stores
Now in order to get your products to be sold, you need customers to be able to look at them. You can do this by placing them up for sale online, which can be done on number of sites. However, an alternative route is to go ahead and talk to a local action figure dealer, and ask him if he could display and promote your products for you.
If your items are rare, he might even be able to find some buyers who would be willing to pay over the top for the items.
The last way for you to get your figures out there, and to have them selling for a high price is to have them auctioned off. You are going to have to find an auction house where they deal in rare figures and then try and get your items sold there. Should things kick off, you could end up making a whole lot more money than you initially planned on.
