Here's another tid-bit of information regarding rarity factors of other Mass. bottles.
(Reference the list below with the one above).
Blank = Relatively Common
S = Scarce (20-100 known)
R = Rare (5-20 known)
RR = Very Rare (1-5 known)
U = Unknown to exist
This listing is for "embossed" bottles only from around 1915 to 1965. The first painted label, (ACL), was in 1957, but it took several years to phase out the embossed bottles that were in circulation nationwide. Also, for anyone attempting to collect "every" variation of embossed bottle, (including every state/city and change in embossed patent info), at last count there were over 2000 different one's. Most collectors focus on their particular state. Here in California where I live, there are about 300 variations. I remember in the mid 1970s this old-timer bottle guy had a warehouse full of these 6oz. bottles, and was selling them for $10.00 per 24 to the case, which even included the original wooden Coca Cola cases they came in. Of course, times have changed over the past 30+ years.
As for value, the best rule of thumb is ...
"Rarity + Condition + Supply + Demand = Value."
