If you're really interested, take a look at all the things Tezos is being used for, mostly in France. I don't personally get into this stuff, but there are things happening. Tezos doesn't meet your criteria as it does have a coin, but it's more of a utility coin than others.
These voting and real estate securitisation projects look to be quite small-scale, but they also seem to be real-world and not prototypes, so they are what I asked for :)
I think this stuff is still very much in its infancy. I look forward to seeing more as time goes on -- the Tezos community has always seemed more focused on this than "price price price" like some others.
