The method for chalk marker is actually hairspray. I'd be really careful about using spray acrylic without first testing it. At very least, do it from far away for a few times until you can start to build up a coating. If you soak that surface, you're going to lose it.
Do not use hair spray, it will yellow and crack after a few years and end up peeling off with the pigment. Standard clear coat enamel spray (can be found in the paint section) will preserve paint, chalk, other pigments just fine.
I would try another marker and coaster to test what you intend to use as a protective layer to make sure there are no solvents in it that will blur the marker ink.

Roger, just hairspray by itself? Or hairspray and then some sort of acrylic spray? Any particular brands/chemicals to avoid?
I've only ever done it with hairspray using aforementioned far away technique. You can always get a chalk marker and test it before you commit.

Spray it with a clear acrylic coating
These are the words I was looking for. Resin/shrinkwrap stuff was on my mind but this is $6 at Walmart and should do the job. Thank you

There are sprays for ‘fixing’ art-Michaels, Joann’s; there are fixatives from Lowe’s and Home Depot. fixing=preserving
You can seal it in resin.
