[QUOTE="John Burgess, post: 4851119, member: 105098"]Yeppers. West Point has vertical presses, Denver and Philadelphia have horizontal presses. ALSO, West Point is normally striking bullion and proof coins, which are normally a higher pressure and this could also be the cause of the better strikes. As far as W quarters go, they strike 2 million of each design maximum. while I have for 2019 Lowell design the mintages are: P = 165,800,000 D = 182,200,000 there's a few factors at work here. Different presses, possibly different pressure settings, much less quantity produced and slower production, and likely an attention to detail the mass producers don't have. From what I can find, San Francisco has Graebener GMP 360 TK press with the dies oriented vertically as well. I am not sure of the model press that West Point Mint uses, but it is a Grabener also. It's likely the same model though, I'm just having difficulty confirming that. Philadelphia and Denver use Schuler horizontal presses.[/QUOTE]
