This is an interesting find
I think it could be company script for a Naval Store / Turpentine farm.

A Sticky Situation: The Turpentine Industry in North Florida
Hello Bramblefind. Nice! I think you nailed it! I have been researching this as a Clermont, FL merchantile token and not so much by the name "D. G. Crenshaw" no wonder I was not finding a lot of info. It is not really a trade token at all and is more like a commissary note in lieu of or instead of pay, hence (as wife points out) the "By Consent" bit.
Your post tip has opened up a whole new arena of extremely interesting historical significance to this piece. Thank you!!!
I have found a double-combined $#!+ load of data regarding post Cival War indigents, convicts, immigrants, and poor blacks and whites basically being conscripted into questionable, to put it mildly, hard labor.
In days of sailing ships, turpentine "farms" provided the base for resins, paints, and chemicals used to preserve rope, timber, sails and etc. employed in the maritime industrial biz...and it looks like business was good...especially if you could trap your "staff" into services and merchandise instead of fair hourly pay. It also spawned another whole industry of equipment needed to collect, store, and process the commodity...pine tree sap. Then there were the narrow gauge railways contructed and maitained to transport the stuff.
I have heard of this part of Florida's history but never found much significantly connected with it. I often find pieces of clay turpentine pots and I do have a complete pot in my coolection. The owner of a Central FL farmsite where I used to detect gave it to me. He said he had 100's of them and found them all time as a kid. Back in the day workers would hang these from nails on pine trees to collect the sap after chipping the bark away. See pic.
Anyway sorry for the long reply, but this piece, if authentic as described, will go in my top (25) special finds...maybe my top (10). Being worth a buck of merchandise in 1890's, it must have been valued highly, that explains the small hole the piece for safe keeping on a string around the short-time owner's neck. To know that a conscipt, convict, former slave, or indentured immigrant may have owned this thing is over the top.
Thanks again and may the finds be with you.
Sincerely, C9
? Daniel G Crenshaw was my great great grandfather, and I'm the person quoted in the Bramblefind's comment below! It makes sense you found it in Clermont, that was the last place he lived, at the turn of the century. He was a very prominent man. I would pay you for this! It would mean so much to our family.
