To the beverage consumer, glass bottles have many advantages over their soda container counterparts (plastic, namely) and are generally more collectible. Apart from the purer, crisper taste of contents that is provided by glass containment, glass bottles stay colder for longer periods of time, are more physically substantial and simply look better when made part of a soda bottle collection.
The early 1970's experienced a wave of environmentalism that brought with it an emergence of glass bottle recycling programs incentivized or mandated by many state and local jurisdictions. In 1972, the famous (or infamous, depending on your point of view) "bottle bill" was passed into law by the state of Oregon that required consumers to pay a deposit during the purchase of beverage bottles. The deposit could then be redeemed when the container was successfully brought back for recycling. The resulting "Money Back" or "Return for Deposit" bottles subsequently became available in many other environmentally-progressive locations, forming one of the two main sub-categories of glass bottles exhibited below.
Depending on condition, some "Return for Deposit" bottles were sterilized, refilled and restocked and others were simply used for their glass content in the fabrication of brand new bottles.
Geographical jurisdictions that did not mandate deposit recycling programs still allowed for the production and distribution of "No Deposit" one-time use bottles, which had a significantly different look and feel compared to their returnable siblings. These bottles were composed of a differing (and less robust) grade of glass and typically had markings that indicated that they possessed no deposit refund value. As a general rule, designs of these single-use "Throw Away" bottles are harder to come by nowadays for the collector due to their intrinsic lack of value at the time (large amounts of "Return for Deposit" bottles were saved by consumers and conversely, large amounts of "No Deposit" bottles were discarded).
The labels that adorn the bodies and necks of PiBB-brand glass bottles have come in five (5) basic forms:
ACL bottles are more frequently associated with "Return for Deposit" programs while Embossed, Styrofoam and Plastic-Coated labels were mostly present on "No Deposit" bottles. Paper-labeled bottles can be either. Old ACL and Embossed bottles are the most widely obtainable today and the others are rather uncommon. Plastic-Coated bottles are, by far, the rarest of all label types.
Unfortunately, due to production expense cut-backs, glass bottles of all types lost the battle against plastic bottles and soda manufacturers began phasing out glass in the late 1980's. Plastic now makes up the overwhelming majority of soda bottles produced (of all sizes) and glass is seldom seen these days aside from the occasional novelty issue and specialty glass-only soda brands. Mr. PiBB of any kind is no longer available in glass.
