I love those arcs as fracs. Not a fan of them as the $5, simply because they have only 2 colors, while the awesome silver sevens $1 has 4 colors and I think that would feel awkward progression wise.
However one thing I'm not a fan of in this lineup is the condition mismatch between the ESST(?) T25s (AND likely the Jack snapper) compared to the rest. I hate mixing used and minty chips in the same set. It's one of my biggest points of chipping OCD, so YMMW, but please do think that through closely before you decide. I would 100% ditch the ESST(?) $25 and likely the Jack snapper as well based on what I can see from your pictures. The jack snapper seems to go 19-20 vs the other chips. (They are obviously awesome chips in their own right though, dont get me wrong), but those mixed stack heights tilt me to no end. They also make stacking and counting chips harder and annoying. That might not be a huge problem though, considering its mainly for your higher denom chips and people are not super likely to have multiple barrels of them all at once. (Depends how big your game plays I guess)
I do like the 43mm suggestion on your top end for your €50 chip. Feels substantial compared to the rest and a proper value storage, almost like a plaque. I know some people dont like mixing sizes, but that I dont mind at all. Only stack heights worry me, lol.
