Just found, question on value

[Marc26]

Thanks for the info Andy. I do have one to sell, and one to keep. The value of the one to keep is much higher because it has meaning to me. The one to sell does have some realistic price and I appreciate the suggestions from everyone. I'll have to see what the market will support. I've seen plenty of empty bottles, rarely bottles in a box, with the papers, and that are full.

This is my bottle. Sadly, it's aqua and not cobalt. I've always wondered what the dates on the bottle mean. Is it the date of the patent?

Clare, Yes, this is the patent date. I think that it is commonly confused with the production date, at least according to listings on eBay.
