> I was wondering whether forgers mix and match between pressed and struck.
I don't know, but I'd have guessed any given source is more likely to stick to one technique they are familiar with and have the equipment for,.
Luckily with LRBs there isn't much care put into fakes, and not that many varieties around, so fake detection seems to be mostly a matter of recognizing known fakes types. Of course seeing double die matches should set you on alert too, since they're relatively uncommon with genuine coins, and certainly odd looking surfaces (presses) would be another tell.
