Franklin Mint is a con. They make people believe they are buying special items but they won't be worth anything for at least 50 years. They are still mass produced rubbish in a posh box!
That would be the enthusiasts website! Best I could find. That's pretty close though And off course ebay has got sellers advertising with photos of the boxes
you can find these at most dollar stores, department and toy stores, Franklin Mint and Danbury Mint make nice die-cast ones with retractable tops. you can usually find them on Ebay
