Those are nice examples of the
type, 186. (And helpful examples from CN, Mark Fox.)
I immediately recognized your first coin by
type, since I've come across those same ones at least a couple times. Unfortunately I was not able to dig any of mine up yet when I went digging around, but hopefully I can post photos later. (I really love these tiny little
imitative horse & dots ones.)
Gorny & Mosch sold several enormous group lots of them in their
Auction 233 in 2015, lots 2944-2947 included >750 coins total, many or most being of this
type. Here's

I believe there may be a continuum of imagery between the official and the most Celticized, or at least an array of different imitations (as with many other imitated
types). I suspect my two examples below are imitatives, but closer to full size and official imagery. (The first I think I sold years ago but
still have this photo, the second I just photographed now) which are a
bit closer in
style to official, but which I've always believed were imitations. I suppose the first could just be a
legend variation or blunder I'm not aware of (MATK- instead of MAPK-):
16mm, 4.3g for the first, 14mm, 3.47g, 3h for the second.
