A tiny bronze (94% Cu, 4% Sn & 1% Zn) coin coin with 17.50 mm diameter and a weight of 2.00 gr. Germany 1 Pfennig 1874 A (Berlin) Jaeger No. 1 Uncleaned, scanned with a resolution of 3,200 dpi and finally saved with a resolution of 600 dpi. The coin was inside a coin frame during scanning process. Condition vf to xf, what is above average for that coin type. Usually you find coins with the small imperial eagle extensively worn. That particular Pfennig in principle remained legal tender until 1942. Multiple die cracks. That happend quite often with small diameter coins.

That will be changed soon I hope...

To be honest, I have to say that lustre can be shown by scanning as well...

Wow!!! You analyzed and optimized your method in a scientific manner!! Now wonder you spend years in that kind of project! I have tried something similar (with scanning) and made thousands of images over the years already.

It depends on the capabilities of the used scanner I think... I received a set of 2003 silver proof pattern a few days ago. Made some scans including the edge with five tiny hallmarks

Well... both is possible. In Germany for example they struck the edge lettering first and the obverse and reverse design is driven into the metal surface afterwards. In UK coins were minted with a collar as far as I know.

Japp, if you promise not to burn me on a stake, I admit that kind of wizardry...

Lets start then...

well... because most people here are coin collectors and not prifessional photographers? I had a look onto Goodman´s web side. The posted pictures are outstanding! The coins he showed are exceptional in grade and value. A professional photographer does generate his/her income by making images of such coins. It would be far too expensive to let him perform images of my common coins for example. For the common coin collector a scanner is first choice. It is easy to handle in addition to the fact that nearly every owner of a computer does have a scanner as well. So it is obvious to use a scanner. And with experience and the right hard/software in hand you are able to produce acceptable images as well.

To find a way to show this edge is clever. But nothing is free of charge in life... In order to achieve something you have to invest work and patience in advance. You might find a device for photographs, which does that kind of images quickly. But you have to invest a significant amount of money then.

Then please transfer the interesting post, please

You are right! We should either split that discussion into a second thread or you guys may contact me and discuss your issues via PM. But so far I want to answer the previous questions... Well, for showing the edge with a scanner you need a lot of patience and you have to perform a lot of work. That image a the edge took me three dozens of single scans plus three additional hours of puzzling the single images into that big one...

@Peckris What do you mean with settings? Post-scan I might adjust brightness and contrast, sharpness and the depth of color... By the way, using a scanner and Photoshop it is possible to show even this:

An hour???!!!!! Heavens to Betsy! I have never scanned a coin so I have no idea ... does 2,400 dpi take 1/5th of that time then - 10-12 minutes?? Well... the scan process at 12,800 itself would not take one hour, but the computer has to calculate the result afterwards. The amount of information would be as enormous as a Brontosaurus... Scanning & calculating of both coin sides at 2,400 dpi takes 5 minutes depending on the coin size and the calculating computer.

I have the information now: Well... I have an Epson Perfection 3490 Photo at home. It is possible to take scans with a resolution up to 12,800 dpi, but it would take around one hour to perform a scan. Usually I scan in with a resolution of 2,400 dpi. Scans are subsequently processed with Adobe Photoshop Elements 5.0

As long as you do not alter details of the coins in respect to the rest of the coin you are fine. Light exposure and angle of illumination is the same for a scanner. And a scanner is very accurate in showing the features of the coins surface

In addition to that you can enhance the saturation of the toning with useful tools like photoshop. So you can adjust the appearance of a rainbow toning if necessary

Simply look at the pictures I posted in this topic. You will find toned coins posted as well
