It appears that they are correct about this piece, with the biggest tell being their secondary point about the misshapen column lettering... also the rim/denticle area.
However, their opening, primary point about "see how weakly struck it is and all the detail is missing?" is off-base. Anyone semi-familiar with these knows this Standing 1850s Costa Rica coinage is notoriously weakly-struck in the center - a quick review of authentic examples quickly proves this.
They cherrypicked a MUCH higher grade piece (less circulation wear - UNC or very close) that ALSO happens to have received a much better than typical strike. It in fact is rather unusual to find a VF-XF piece with more than just a trace of skirt detail.
Here, as a fairer comparison, is a piece that NGC straight-graded XF45 (which was generous as it pretty much looks textbook ex-jewelry surface, seems to have an ignored mount mark... plus not sure if that's notable scratch or a die crack). A much closer match in circulation wear to what was the model for the fake piece... and just look how blunt the center is.
