Going by retail with tax prices (not what may have been paid under/over or current valuation): just over $4,000 and I don't see it going any higher anytime soon either. It's ebbed and flowed over the years and will likely ebb again if I had to guess. At my peak back in 2010 the amount would have been more like $12,000
When I die someone will look at what I've collected and say, Look at all this junk? You're uncle was crazy! I on the other hand will be laughing as they accept a dollar for most things at a garage sale.
This thread was created on March 5, 2013. I'd be afraid to see what some of these collections are worth now 3 years later after reading through all the comments.
Off the top of my head I'm over $3,500 and almost all of that was bought with discounts. Not sure what it would have been retail, scary enough that's a discount price lol.
