From I think 2010 or 2011, the mint use horizontal presses. Are faster and deteriorations are less. the way it is work: The reverse is head up and Observe head down. Down we have around 1.5 to 2 tone more forces which was observed could crack the plating and also the planchet. This I think it is the reason we can find same thing on different years. Just Physic's.

Great set of eyes for finding the pair.

Spence, I am definitely keeping them together. Once I found the first example years ago, I had only been closely checking the 2015 coins, but I realize from the COC lists that spikes can happen any production year.

Silviosi, is the Reverse up positioning also used in Jefferson nickel stamping? They have a chipping problem on the reverse at the edge walls of the Monument building. I have a whole tube of them with chips.

Lol. ( You Old Codger ) ( I resemble that title) that's really a cool for finding your second one in so many different years. It is pretty cool to find the same Spike. How bout the markers do they match? I've come across Spikes that I've listed with Cuds but with different reverse markers. Are you going to send pics to Cuds? You had me check my 2015 P. I have two nothing like yours. One really weak at rim both not listed. Coming from Vegas now in Idaho just don't run across to many Philadelphia. Again that's pretty cool to find the same. Nice pictures.

The chances of finding the same die pair can be good, even years apart, in the same local area. The boxes of rolls that contained this error should have had multiples of this die pair in it. Coins can , but in this era of credit/debit cards, don't travel that far.

Rob0411, I have a similar problem finding Denver coins on the East Coast, particularly since the pandemic seemed to tighten nationwide circulation. As for markers, the first coin had none while the later sample had a small Cud from the first T in States to the rim. I tried all weekend to submit images to Cuds, but my photo editing experience failed 3 entries. The close-ups were "unusable, pixelated and out of focus". But I'll keep sending pics till I badger him into submission or I get a cease and desist order.

Silviosi, thanks for your answer. So the modern Jeff nickel just has an unfortunate design.

I sent a 83 Lincoln in a couple weeks ago. JC replied that he got it and let me know the results. I just figured it's vacation time and probably take a little longer. Do you have this app so to size your pictures? It works great for me. It's free but they ask if you want to upgrade to stop adds. I have not and it's been years.

Rob0411, thanks for the app suggestion, but that looks like an Apple Iphone app while I'm using an Android phone for the shots and the MS photo editing capability. I've also tried using the Irfanview program that COC listed, unsuccessfully. I'll work it out eventually, whether I should start with a macro image or magnified standard photo, then what happens to the pixel quantity when resizing to the different COC size requirements, etc. Maybe an old dog can learn new tricks.

@Old Codger NJ. No the nickels, and others coins in those days have very complex design. So the hammer and the anvil will be change according with the complexity of the design.
The Anvil it is more stable then the hammer.
why this? Because on the strike the forces will split from center to the sides, The anvil it is the Die who take all those forces and split. If you have only the head of pres. will be less distortion on the design. So in fact it is the mint want the most clean strikes with full design and no strike flow of material on the very tinny and delicate design.
This case do not apply to all coins, but hoe the go now I think will be like this. Do not forgot the hammer Die punch (apply the strike forces) and the anvil receive and dispatch those forces.
Hope you to understand the physics of strike.

Yep Sorry didn't think about that. It is an iPhone app.

Silviosi, I was only questioning why the chipped ends of Monticello became much more common after the 2006 Franki obverse redesign and the President was moved off-center.
