So, overall, what I have to say about Worth Point is that it is not worth your money for a number of reasons. First of all, Ebay auctions are not a reliable source for the valuation of your vintage items. Secondly, they base the worth of your item off one auction that closed (in my case) more that three years ago. This does not seem like a realistic valuation of my items. In looking further into Worth Point, it seems that what they do is pull values off different internet sites like Rubylane or Tias or Ebay. So if I have the same item that you have and I have no idea what it is actually worth and I price it at $25.00 on Rubylane or Tias, Worth Point will pick up the sale and state it as a value on their site with no extra valuation expertise or experience. I suggest instead, going directly to rubylane.com or tias.com or etsy.com to get the true internet value of your items. If you do the footwork yourself and take an average of the value of the items sold or listed that are like your item, you will get a better idea of value than if you went only to Worth Point. In addition, you should consider buying some of the many valuable resource books that are available to the general public on the topic of vintage collectibles.
These sites will give you a more realistic view, however, not the full retail value. That is because they are malls with many competing vendors. That is why the values at these sites should be consistently less than book value.
I will continue with my "free" trial and let you know how it plays out. Hopefully I will find some worth in Worth Point.
