The amber straight-sided Coca Cola bottles were generally made between circa 1903 and circa 1915. Because your particular bottle has ROOT in capital letters, it should date between about 1906 and 1909. Between about 1901 and 1906 they marked their bottles with either RGCo or RGCO. In 1909 the Root Glass Company in Terre Haute, Indiana started dating their bottles, such as ROOT 12 for 1912. According to Bill Porter's book, amber Little Rock, Arkansas Coca Cola bottles are considered somewhat common. According to Cecil Munsey, the Little Rock Coca Cola Bottling Company was established in 1903. As for value, in excellent near mint condition my guess would be about $100-$125
The 922 is not a date code but is a "model" or "style" code. Date codes were two-digit numbers such as ROOT 17, ROOT 22, and so on that were first used in 1909. Check out the information on this link on how to date early Coca Cola bottles ...
