You can find some good information regarding how to identify reproductions along with some pictures of known reproductions from various online sources. If you are interested in learning more about these bottles there are two books currently available that provide some excellent information about how they were made and used along with some basic pricing information. The book are titled "Udderly Beautiful" and "Udderly Splendid" by John Tutton. Both give some rarity and pricing information but because of the large number of bottles produced they don t cover even a small fraction of the bottles produced. Both can be found for sale on either eBay Amazon or in some antique shops. Other sources of information are The National Association Of Milk Bottle Collectors and the individual web sites many of their members maintain.
Do not let the fact that a bottle is from a state that is known as a diary state dissuade you from buying it. Many of the bottles from these states are rare and command high prices. Bottles with more than one color will usually bring higher prices. Bottles with attractive graphics on their reverse side will often bring higher prices things such as babies; war related themes patriotic themes and herds of cows are just a few things to be on the lookout for. A word of caution In the last several years reproductions of some milk bottles have begun to appear more and more. Fortunately the vast majority of reproductions are of other types of milk bottles but there are reproductions of 1 quart Pyro-Glaze milk bottle as well.
Over the years I have found that on average for every (10) of these bottles I purchase I will get the following results: Three of them will sell for hefty prices that allow me a profit of $100 to $150 or more each Five of them will sell for prices that allow me a profit of $20 to $100 each Two of them will sell for prices at which I either break even or loose $10 to $20 each As you can see there are times when I loose a small amount of money on some of the bottles I purchase. However I m willing to take those losses due to the much larger profits I make on some of the others. In the end I make money overall. It is important to understand that if you are going to take some small losses on some of the bottles you buy if you choose to get involved in this eBay sub-niche.
