Is this at all common? I only recall having seen it at one location.

It happens on NY 206 near Roscoe. The entire route between NY 17 and NY 30 is county maintained. Also multiple locations on NY 155, since much of the route is maintained by Albany County.

There are two major reasons for this:
A real overlap, where the two routes merge and split. Florida and New Jersey often sign these. (I don't think the I-295/CR 551 overlap is signed, however.)
An indication that the state route is county-maintained. This is the reason for most (all?) examples in New York, and presumably the Missouri case.

...New Jersey often sign these. (I don't think the I-295/CR 551 overlap is signed, however.)
This is as close as it gets...and the sign is wrong anyway (it should simply be 'South 295/South 551'): https://goo.gl/maps/ic96tnpQY5S2 .
Going Northbound, 551 is never signed on 295 itself. On Hook Rd (551), there's a small, faded shield showing the way (https://goo.gl/maps/QPrKW9KBD4U2) onto 295 North, but if you seriously wanted to follow the route based on signage, you'll miss your exit (2B-C) as it's only signed for US 40. There is a SGS on the ramp however.
One of my favorite examples is down the street from me on a state-maintained highway. McDonough CR 8 is signed along with IL 110 and IL 336 in Colchester. CR 8 is on a short concurrency through here and it signed well.

Monongalia CR 857 is co-signed with US 119 and WV 7 in the Morgantown, WV area. It's one of the few county routes in West Virginia that gets free-standing signage.
Though there are innumerable implied overlays of primary and secondary routes in Virginia (mostly 0.1 mi or less), I can only think of 3 off the top of my head that are truly posted as a co-sign:
VA 285 and SR 608
VA 185 and SR 675
VA 208 and SR 608 (Spotsylvania)
Perhaps there are a few more...
There's at least one good example of this in Minnesota: MN-55 and CR-101
(https://i.imgur.com/HrTT6tC.jpg)
CR-101 used to be MN-101; the signs are only there to maintain continuity of the route. However, the same can't be said of the "overlap" between 101 and MN-5 further south, which isn't signed.

I would be interested to know a definitive answer on this one.

Hmm. As much time as I've spent in that area, I don't think I've actually driven that section of MN-55. My route west from I-494 has always involved US-12 instead, so I've only driven MN-55 in and around Buffalo (and near Hastings). But I knew there was bound to be a Minnesota example, as soon as I started the thread.
On Long Island, the NY 27/CR 39 multiplex is signed at this point. I'm pretty sure that there a batch of similar situations upstate as well.
Here in Wisconsin, especially in rural areas, it is very common for there to be short concurrencies between a county and a state or federal highway. The county highway joins the bigger highway for a few tenths of a mile before splitting off again.
US 27 and CR 561 join up for a bit in Clermont, Florida:

Actually happens quite a bit in New York. If a county signs their CRs, you can bet that a county-maintained state route will be signed as a CR. Valerie mentioned NY 155 and NY 206, but those are far from the only ones. NY 28A and 213 in Ulster County are co-signed (28A has old outline CR shields as well (https://www.google.com/maps/@41.9776116,-74.0911891,3a,16.5y,205.15h,81.66t/data=!3m6!1e1!3m4!1swEv4AVTqephoZPWjTzzUTA!2e0!7i13312!8i6656)). NY 40's county-maintained section in Brunswick is signed as Rensselaer CR 145. About 2/3 of NY 254 is maintained by Warren County and it has two separate CR designations, each signed. The section of NY 27 maintained by Suffolk County east of where Sunrise Highway ends is co-signed. NY 3A in Jefferson County? Yep, has CR shields as well. Cattaraugus County's section of NY 240 is 100% county-maintained and every state route shield is mounted over a CR shield. Heck, even Erie County, which has fewer than 10 CR shields left in the wild, has one remaining on the section of NY 240 it maintains (at least it was there the last time I drove by).

Ulster Co. NY has a few, County road 4 and NY 213, NY 299 and County roads 7 and 8

I believe US 33 has a couple of secondary route concurrencies between Harrisonburg and Elkton.
EDIT: Just one, with SR 655 (https://www.google.com/maps/@38.379299,-78.7983914,3a,75y,180.49h,76.8t/data=!3m6!1e1!3m4!1s90TOqyPqWBqb970rm4B5yA!2e0!7i13312!8i6656).
EDIT 2: The other one I was thinking of is just outside Elkton, with SR 634 (https://www.google.com/maps/@38.393439,-78.5968636,3a,75y,215.46h,81.22t/data=!3m6!1e1!3m4!1sgxTkeWg0gkiVrrNLFEL1Fg!2e0!7i13312!8i6656).
How about with a (normally hidden) state route and a US highway?

Not necessarily. The signage for NY 27/CR 39 is relatively new. Before the construction work to get rid of the Shinnecock Squeeze, it was just signed as NY 27. Suffolk CR 39A is multiplexed with NY 27 for its entire length, and as of the last time I went through there, it's still unsigned.
Suffolk is a weird case in that it doesn't sign all of its CRs, either. Quite a few are unsigned. Might be the only county in the state that isn't all or nothing at this point.
NY3A is maintained by Jefferson County, and is also signed as CR36. It is mostly used as a bypass of Carthage.
Of course, NY3A may soon be decommissioned if the Fort Drum missile defense site proposal is accepted...

NY 3A hasn't been decommissioned yet? That might be the only county-maintained state route remaining in Region 7. They've removed most of them (and replaced the relevant signs along the Northway).

Thats a find!
A lot of county roads in Florida used to be Seconary state roads. Where they multiplexed they sort of became full fledged SRs.
Although a lot of the muliplexed segments of CRs are not signed at all.. You see 2 junctions. (i.e. SR/CR 224 in Clay County multiplex with SR21/Blanding Blvd SR224 is Kingsley Ave and CR 224 is College Dr)
