Both mints predominantly use Schuler horizontal presses but I believe they do also still use some of the older presses for business strikes. Since 1996, Denver has had its own die shop so they may use a slightly shorter life cycle for their dies vs. Philly. As far as bagmarks, both mints have been using the the Ballistic Bags that hold 400,000 cents for over a decade now and this handling method has caused the average grade of business strike coinage to drop a point or two. |

400,000 wow! What about for the Half dollars? How many of them fit the Ballistic Bag? |

I receive the ATB Quarter rolls from both mints every time they come out. I have definitely noticed that the Denver coins are much better. I think the strikes are both ok, but the amount of post strike marks on the Philadelphia quarters are much higher. |

Maybe something to do with the altitude?
Im sure theres other reasons but thought the altitude possibility would be fun to throw out

My calculator says that 400,000 makes 160 boxes. 140 boxes make a ton. So 160 boxes are approx. 2560 lbs.

Do they all have the same machines? Could it be the layout of the minting rooms, maybe the conveyors are different?
There's not any one reason. Denver is simply better run and operated than Philly as it concerns coin production. However it should be noted that coin quality from both mints form a sort of bell curve. Whilwe most Denver coins are superior to most Philly coins the Philadelphia mint makes some of the finest coins out there. Look at a few hundred 1971 mint sets and you'll see the finest quarter will be a Philly. This occurs in many other dates as well. Nice Philly issues are extremely tough for many many dates but when a nice one is found it can be stupendous. Time don't fly, it bounds and leaps.

Due to the altitude, the air is lesser poluted with STUFF. Therefore the metals used to make the coins in Denver have less dirt on them. Dirt doesn't like to go upward so places like Philidelphia get the higher quantity of dirt floating around during the making of coins. And once a coin is made in Denver, again the air is so clean, the coins just look better. Also, with less air presure it is easier to make coins with the slightest press on the presses. This too helps avoid press problems. Please note all of the above is utterly rediculous which means I really don't know.  |

I don't like to think about my city producing bad coins because when I visit this summer I'm hoping to get some better quality coins then what I've been finding in Alaska

Has anyone factored in the location they receive the coins? I would expect that living on the east coast would get you Denver coins that are worn more and appear worse in quality, whereas if you live on the west coast it would be the opposite.

Still fairly new to this whole thing but I certainly noticed a big difference in the strike quality between he mints while searching my box of nickels. It seemed that almost every nickel that was extremely well struck was from he Denver mint. Bag marks and such seemed to be pretty comparable.
I have to agree, just_carl has the best answer by far. I am going to recommend that we adopt it as the official answer to the OPs question.

Yes. Coins that travel across the country almost always are down to high end AU but the quality issue applies to uncirculated coins from both mints. It's not only the quality of the coins but production qualities as well. Note that most of the DDO's and other error and variety coins issue from Philly. They simply are not doing as good a job as Denver on any parameter. We should keep in mind that a great deal more work goes on in Philly and this could play some role in the difference. It's possible Philly operates on some other playing field but their coins don't come close to Denver in quality. The difference has narrowed substantially in recent years but it still exists. Time don't fly, it bounds and leaps.

Denver has more smog than any city I've ever seen. I was amazed the first time I saw it.

I think it's our clean air and fresh Rocky Mountain Spring water !!
Seriously, over the years I have found a number of business strikes from the Denver mint that have mirror-like surfaces. I always have to look twice to make sure these are not proof issues that were put into circulation.
All of the recent D mint pieces I have in my collection are pulled from circulation, and many of them are gems! Unfortunatley, I usually don't start seeing coins from Philly showing up here in Colorado until late in the year, and these are usually fairly battle worn by the time they circulated across the Mighty Mississip. I'm sure you folks in the Eastern US experience the same thing with Denver pieces.
