I've started doing Stack and Stitch technique for my coin photography. It's very addicting! The images are difficult to host and view effectively due to their large size, so I have been using the EasyZoom hosting site for my images. Here are some links to the latest ones I've uploaded. When you view them, I recommend going full-page (upper right icon in EasyZoom page) and of course zooming-in to see the details, which is the whole point of going to this much trouble. Note these images are 180MP (18800 x 9600 pixels) so you can zoom way in on them. You will get to 100% pixel detail after 4 hits of the + zoom icon, or double-click 4 times where you want to see. Enjoy!

Hi Ray,
great work indeed and I lift my hat!!
But allow a simpe, question: coins do not really show much great details (like an insect or bettle etc.) which would require such great detail in my humble opinion, so it is just "because I can" or what drove you to that 180Mp resolution? _________________ Klaus - Admin

Interesting bit of detail in your second set of images. The "4" in the date appears to have been sheared away. Wonder how that happened. Maybe the rest of it got stuck in the mold? Mystery! _________________ Michael

Sorry for late reply...I am used to other forums alerting me to replies by email. Is there any way to turn this on here at MF Lenses?
This level of detail is actually very useful for coin photography. Indeed this does not go quite far enough! I often shoot coin details at 5x and 10x magnification, and have done many "3D" perspective renderings and animations in order to show certain variety details, such as RPMs (Re-Punched Mintmarks) or Doubled Dies. You can see some of this high magnification work at my image gallery, http://www.macrocoins.com/image-gallery.html
What I've found, with the right lens (95mm Printing-Nikkor operating in reverse at 2:1) and the excellent hosting site, is that with these images I can fulfill a decade long goal of having a single image of a coin which has sufficient quality and detail to show a die variety along with all the subtle detail around the coin needed to identify the die state (amount of die wear), die stage (snapshot of the progression of die damage, chips, gouges, scratches, breaks, etc which happen over the die life), plus show the coin in an aesthetically pleasing manner. These first images are not as detailed as I'd like, but they do fulfill the goal in spirit, and have proven useful already in documenting some interesting coins. _________________ ...See my Numismatic Photography website at: http://www.macrocoins.com

I think that was caused by a "filled die". Sometimes hardened grease will get caught in the incuse die features and will keep the planchet metal from being fully struck-up into the features. _________________ ...See my Numismatic Photography website at: http://www.macrocoins.com

Coins are struck with two dies, an obverse and reverse. The dies, even when new, each have unique characteristics like scratches, gouges, etc. Some have more interesting characteristics like doubling of the design elements and/or the mintmark. As a die wears from striking coins, it will show striking-related characteristics like flow lines, and often will develop localized cracks, or small pieces will break away. All of these characteristics are struck into the coins produced by the die, and each coin struck represents a snapshot of the state of the die at the time of striking. The characteristics which are present on the die through its whole lifetime, such as doubled dies or repunched mintmarks, produce "die varieties". Every coin struck by the die has these characteristics. Characteristics that develop due to striking, such as die cracks or chips, produce "mint errors" or "die errors". Usually a die variety does not result in the die being taken from service, but if mint techs see major mint errors being produced, the die will be replaced. _________________ ...See my Numismatic Photography website at: http://www.macrocoins.com
