Today is the start of Mardi Gras for 2016.
The capped bust half dollar above is 1827, the first year Mardi Gras was celebrated in New Orleans.

around the peripherals, (the stars, date and letters) and dirt is still trapped in the fine lines of the shield on the reverse which would make it worth twice as much as the 150 or so i got it for, if i send it in for certification and they assign it a numbered grade instead of xf or so 'details'
