well, I have looked up some items in a Disney toy catalog, but many just aren't listed. I would suggest you do some checking on Yahoo and Google, by just typing in what kind of items you have and see what they are selling for. I sell most items on eBay, but always check to see what the same or similar item is selling for. Sometimes you can really get a jolt. For instance, I had a 1994 Minnie $10 Disney bill that was in the envelope that I purchased with it, and I posted it to sell with my opening bid to begin at $10. A very nice person contacted me to let me know that it was worth several hundred dollars, and that I should be careful of someone wanted to 'buy it now' for a much lower number, which did happen. Almost immediately after posting the item a man contacted me and asked me to let him 'buy it now', which ends your auction, for $50. Now, that sounded great since I was only asking $10, but thanks to the man who told me it's worth, I left it on auction and in 7 days, received 41 bids, finally selling it for$347.90!!
So do some foot work, and you might just post a 'Hub" on looking for the value of the item. Also, if you tell me specifically what items you have, I may have their value and would be happy to let you know. Take care and good luck.
