Poliquin variety 20 for the date, with heavy die cracks around the entire Obverse, and significant cracks on the Reverse.  Looks to be a fairly late die state.  On top of that, this is an attractive coin with evenly toned brown surfaces, with some tiny hints of red toning in a few protected areas.  Not much to note on the surface other than a small area of grunge below the '18' of the date.  More images available, upon request, as I am limited in how many I can post here. Hard to say how to price the variety, so I have tossed out a number and added a Make an Offer option.
