I seem to not be able to correctly identify a doubled die on a coin. Do the notches in this photo correctly show a doubled die?  |

The question: What is doubled? The devices are normal in size. If you are using more than one light you can get refraction that is distracting. (Not saying you are using a double light, but a single bulb light gives the light and shadows to see what is really there) But I do see the light on both sides of the vertical devices. Even secondary lighting can show one strong light on the one side of the device, and a secondary source from another direction. (Secondary lighting sources can be window light, or interior over head lighting) I determine the direction of the unwanted light source and then block it with a piece of tape and a tissue, bond paper of even something to preventing the light hitting the coin during photography. Also to cut glare (that creates a white area on the image) I diffuse the light preventing a glare. This can also be cut with the above source bu you can add rice paper, plastic grocery bags and this will remove glare and reduce the light source.

The only light on the coin are the lights in the microscope. I think there are about 8 LEDs. I turn off the overhead light when I take the photos. Maybe this is just not the hobby for me if I can't get the hang of identifying what I'm looking for.

Lighting is a problem for all of us. I had to block off all but one on my scopes and put a filter on that one. It just takes research and practice,hang in there. John1  |

On my scope I had to toss the original lights away from the scope. I reused the previous mounting areas to get the right place for the lighting I changed to.  Don't give up so quickly. It just take patience to find what will work for you. You might try John's suggestion. Pick the light that is right overhead when you view the coin. The rest you could block off. Try that first. Sometimes they have dimmers as another option. Keep trying, if something improves images, go with that. We never get it right the first try. It doesn't all some to you in a few tries. The more things you try, they more you can see what doesn't help. Been there myself. |

On my limited income, I could never afford a scope like that. I just have one of those USB digitals that was given to me.

Here's a couple of tips to improve on a limited budget. 1. Buy a stand for that inexpensive digital scope. Just mounting it vertically in a base that holds it still will help dramatically. I bought one for $20 bucks on Amazon and my photos improved 100%. Mine was manufactured by Jiusion, and there are others out there as well. 2. Buy some alternate light sources. Many on the coin photo threads recommend a desk lamp made by Ikea that has an LED light bulb and long flexible neck. Get 2 (each costs about $12.00) and use them on either side of your scope to flood the coin with light. 3. Use a black fabric background as that helps keep down light reflection. The one thing the little scopes can't handle is all that light coming back at it from the coin and the background, washes things out very easily. The photo below was taken with this set up. It's no prize winner and can't compare to many of the high quality photos on this forum, but for about $60 all in it can't be beat. Plus, since the scope and stand are small, they sit right next to the PC and I can use them to look for doubled dies, RPM's and other errors when I don't need to photograph them.  |

That looks like MD. As for light,I have turned off all the onboard light on my scope and used a one dollar hand held LED flashlight that I put a filter on and it works fine. You can aim it wherever you want on the coin. John1 |
