rmpsrpms Pillar of the Community United States 4038 Posts	Posted 04/07/2012 12:50 am I've started posting "One Variety a Day" photos over on Lincoln Cent Resource forum, and one of the varieties was supposedly "debunked". However, I did not agree so took a high resolution photo of the mintmark to show more detail. The variety is 1951-D/S OMM#2 and supposedly there was an overlay done that showed the secondary mintmark was a "D" not an "S". The photo I took shows it looks more like an "S", at least to me. Here is the link to the thread, and below that is the high res photo. This was taken with my T2i on bellows, with the El-Cheapo 4x 0.1 Achromat objective. The objective is a bit weak at the corners, but I cropped the 5184x3456 image to 3200x2400, then downsized 4x to 800x600 to post. 5-image stack. http://www.lincolncentresource.net/....php?t=20676 Contact me for photographic equipment or visit my home page at: http://macrocoins.com Edited by rmpsrpms 04/07/2012 12:52 am Report this Post to the Staff

rmpsrpms Pillar of the Community United States 4038 Posts	Posted 04/07/2012 10:29 am Does anyone on the forum know how to do overlays? The classic way to prove these sorts of things is to overlay an S mintmark over the image to show how things line up. I'm not big on image processing so am not sure the best way to do it. Ideally I'd crop the S mintmark from another photo, and then paste it over the D/S at perhaps 50% transparency to show how it lines up. Is there a cheap way to do this?

brg5658 Pillar of the Community United States 627 Posts	Posted 04/07/2012 10:42 am Ray, you can do that using GIMP (freeware). It allows for layers, and transparency of the layers. You can also rotate real-time (visually, by dragging the layer to get the overlay correct). That hardest part would be sizing the "S" mint mark to be the correct size before the overlay. You can also do it in Photoshop, but only if you have the software. If you have two large images and would want me to do a "mock-up" for you testing the feasibility, you can send me two large images of the questioned "D over S" and what you think would be the appropriate S mintmark for that time frame (I remember reading once that there are 15 different Lincoln S Mintmarks).

westcoin Pillar of the Community United States 9792 Posts	Posted 04/07/2012 5:35 pm I would use Photoshop, since I own several copies anyways, I know it best, but GIMP should do fine as well. As stated the hard part would be getting the exact size scaling down, then copy the send image, paste it into a new layer align as desired, and change the opacity to a good level to let the original show through, probably around 66% or so, flatten and save as desired file type. A coin cropped with a couple of anchor points should help ie design or rim edge and design, to get the second coin laigned to the same size, this would work as long as you are dealing with uncropped photos from the same camera sized chip and working distance of the coin, making sure the magnification is the exactly the same.

OK, here are a couple images taken at the exact same magnification. First is the D/S in question, and second is a 1951-S example coin to show the mintmark used that year. After looking at them for a while, it looks like the variety is actually a D-over-inverted S. The lower serif of the S is more bulbous and at a higher topography, while the upper serif is much less bulbous and the top surface is very flat versus the field. Would appreciate if you could see if an inverted-S fits with the D/S. Also, please describe how you do the overlay.

brg5658 Pillar of the Community United States 627 Posts	Posted 04/09/2012 12:40 am Hi Ray, If you download GIMP the steps would be the following: 1) Open both files. 2) From the "overlay" file use either the rectangular or oval select tool and select the "S" mintmark. 3) Copy this selection to the clipboard. 4) Go to the file onto which you want to overlay the mintmark. 5) Select from the menus Edit --> Paste as --> New Layer 6) The "S" will now be in it's own layer, and you can adjust the opacity of that layer in the your "Layers Display". 7) You can use the "rotate" tool to rotate the currently selected layer to the correct orientation for overlay, and you can move around the "S" layer by using the "four-way" arrow tool while having the overlay layer selected. I have posted a general "how to use" GIMP on another forum, linked here: http://boards.collectors-society.co...#Post5519626 Here are my first attempts at an overlay. I inverted the "S" mintmark image and then adjusted the opacity to four different levels. 30% opacity 40% opacity 50% opacity 60% opacity I hope this helps some. Report this Post to the Staff
