JadeSpear Valued Member United States 62 Posts	Posted 12/04/2011 7:55 pm Greetings All, New to this forum. Please allow me to weigh in. The obverse has questionable wear signs on the arrow heads, lower shield, and leaves adjacent to lower shield. I see possible signs of friction in the coloration of the high points. Perhaps it is the lighting you used in your shots. I prefer a high resolution scanner or using a macro lens, shooting from within 15mm of coin with axial sources of natural and full spectrum lighting. I also may use a black felt backdrop to force a slight overexposure of my coin. This helps show the details better including all imperfections. In my humble opinion this coin grades more like MS60 slider. Hope my contribution helps. Report this Post to the Staff

Point of curiosity - what macro lens requires such a close focusing distance? Canon's 100mm Macro has a minimum focusing distance of 300mm, and I rarely need to get get closer than 150mm with my 75mm lens for something the size of a Cent. Report this Post to the Staff
JadeSpear Valued Member United States 62 Posts	Posted 12/05/2011 06:41 am Hello, I use a point and shoot Fuji s7000 which has a super-macro feature which allows me to shoot down to 5mm. I can shoot so close I see the most minute metal imperfections and properties. Shooting at a greater distance with a macro lens will not get the near-microscopic details needed to properly analyze the condition of a coin. I also study ancient ceramics. Which this type of detail is essential for identifying age. I believe that at 150mm (15cm) it is impossible to get the detail I like to 'require' for my purposes. I will post a shot from my camera later today. I have to go to work now. Thanks, Report this Post to the Staff
JadeSpear Valued Member United States 62 Posts	Posted 12/05/2011 06:53 am Also Super, my brother is a professional photographer and he has Nikon DSLR cameras and lens and is able to shoot within 15mm. I do not know which size macro lens he uses. He also has my point and shoot Fuji as a quick backup. This is only from my personal experience. As mentioned I've been shooting ancient ceramics diagnostics for the last 9 years. I will post a sample in the near future. Hi ho, hi ho, it's off to work I go..... Report this Post to the Staff
SsuperDdave Moderator United States 23522 Posts	Posted 12/05/2011 10:47 am Ah. Having mentioned the preference for a dedicated macro lens, I'd thought that was your setup. Knowing you're using a point-and-shoot, I quite understand the close distance. Thank you. Report this Post to the Staff
JadeSpear Valued Member United States 62 Posts	Posted 12/05/2011 7:41 pm Hello, I am attaching 2 images of an Ichibu (MS-63) that I just taken with my Fuji s7000 point and shoot digital camera. It has been rated for years as having one of the best built-in macro lens of any point and shoot camera 'ever'. The first one was shot in single macro at a distance of approx. 10" (25.5cm). The next was shot in super-macro at approx. 2" (5cm). Notice the difference in resolution. I used a textured black backdrop for convenience and 2 axial natural light and full spectrum florescent tubes each operating at 3200 degree Calvin. BTW, Because of this forum upload limitation. My file size is severely compromised. Normally my images are 1.5mg and larger. Anyhow. What do you think? Report this Post to the Staff
JadeSpear Valued Member United States 62 Posts	Posted 12/05/2011 7:59 pm Oops! Would help if the 2nd image was of the same side of the coin as the first. Here it is, (Ichibu3), at the 'super-macro' approx. @5cm. Please let me know what you think. Report this Post to the Staff
JadeSpear Valued Member United States 62 Posts	Posted 12/05/2011 8:53 pm I managed to upload the wrong picture again. Here is the higher resolution image from approx. 5cm of the obverse of this Ichibu. Report this Post to the Staff
JadeSpear Valued Member United States 62 Posts	Posted 12/05/2011 9:32 pm Super, you were correct. I was able to shoot at a farther distance than I thought. Normally with appraising ceramics, I shoot far closer as mentioned before. But with coins, I can shoot further. Thanks for weighing in and enlightening me. Report this Post to the Staff
