It's #110 plus whatever the dumbbell (#10 - 15 ) is. They're using the bumper plate color code. That being said, don't see the value for 99% of people. The red 25/55s take up about 7" of a usually 8" Olympic dumbbell sleeve. If you add the collar, you're about out of room to add plates. The people that would be most interested in these are strongmen and odd lift guys, but they're going to pass the weight limit in short order.
These will probably be dust binned soon, unless there's a bunch of middle of the road strength guys that are worried about their floors.
