I've not found & no-one has provided any good references that these groups of 'Revolutionary War Dragoon Buttons' are as described.
There are left & right facing horse back riders, some with swords, some with whips. Various types, that don't follow the usual British Pattern progression, so I'm pretty sure these are NOT Military related.
Others may 'guess' otherwise, but they need to provided the proof that is lacking.
There are more similar Civilian examples like the cuff-link I IDed the other day. So a good starting point is a picture of the shank please?
