The owners of lassie.net have appeared worldwide on various TV shows featuring our massive collections and we have appraised Lassie collections for estates. It's difficult, if not impossible, for most Lassie collectibles to have a firm value, unless they are extremely rare.
Not that long ago you had to scour the antique shops to find anything from the lucrative days of the 50's and 60's when Jack Wrather handled the licensing of products. With the advent of eBay, prices stayed high for these items, but as time went on, and as Lassie's older fans aged and downsized, more people listed their old Lassie items, prices went down, the basic law of supply and demand. Items that just a year ago went for hundreds of dollars can now be found in large supply for less than $25-50. There are no official price guides, and even if there were, they would probably be outdated before they were printed. The current economy also affects all collectibles as prices drop when demand does.
We can tell you how rare an item is, and what we've seen it going for at current market value, and sometimes where you might find it, but cannot appraise anything without seeing it personally.
