Nice coin :) try looking up on old maps or history books about where there were battles, or old settlements , old roads, paths , trails and so on. Don't give up friend. Check out my finds on my blog if you haven't already my newest article https://steemit.com/history/@supernovaone/metal-detecting-silver-coin-find-1668-treasure-hunting
. And one more piece of advice from me, detect around big old trees people would stash there belongings there before entering a town or village not wanting to be robbed, and sometimes they never made it back to collect :)

Peace.
