Shane--to answer your question of what it is, this is a trade token, used in the business of J. F. Hendrix, and was good for 5¢ in trade. His business was probably a pool hall, card room, bar, cigar store, confectionery store, or a combination of those. It is of a specific type (St. Louis part-incuse) that were made in St. Louis, MO over a long period from the 1890s into the 1950s. From the records of the
Token and Medal Society, the reverse of it is "Plain" which doesn't help a lot. Many of the St. Louis makers put their name and address on the reverse which helps date the piece, but some did not. What we do know is that it was made in St. Louis. That helps localize where Hendrix was, but doesn't prove anything. Similarly, where you found it is another clue, but just that. There have been three of these submitted to TAMS, one each from a Michigan, Wisconsin, and California member. I know those members collected tokens from all over, so that doesn't help either. The search strategy is to check city directories and Census records for somebody with that name and in an appropriate business about 1910. Then expanding the search outward, earlier, and later. Since Hendrix is a relatively common name (over 10,000 in the 1910 Census), and we don't have a first name to work with, you can see why this one is still "unknown". By the way, a trade token without town and state is known as a "maverick". The search goes on...
