Most of these items are familiar to recent generations because they have been in production for the last 100 years.

Bottle collecting has become a popular American hobby and bottle enthusiasts looking to add a few new items to their collection can find plenty to choose from at flea markets, bottle shows and at many auctions. There are many categories of bottles—bitters, beer, whisky, soda, mineral water, ink, medicine, poison, fruit jars and historic flasks among them. A rare sapphire blue flask (pictured) made in Bridgeton, New Jersey, circa 1825 – 1840 sold for $28,750 at a Glass Works auction last month. It has a sloop on one side and a star on the other. It's thought to be one of only three of its type known.
