Coins Challenge Coin lot set Collection Military Most Army Signal Corps US. Military Units, DoD Contractors, OIF, OEF, DoD, Army, Marine, Navy, Air Force, military support, government, police. I make NO claims to ANY silver (or any other metal) content of any coin that is in this lot. I’m thinning out my Challenge Coin collection and need to get rid of most of my coins. There will be no Second Chance Offers as this is the only one that I have. Let me know if you have any questions. The size, shape, and weight of your coin will dictate the packaging and how it is mailed. I take ALL photos in natural sun light to try to best capture true color. This can make some softer. Bronzes seem almost grey and shiny gold-tones appear silver. I find the natural sun light gives the best contrast for 3d detail and preserves natural epoxy color. The counter to this is it can also cause a glare at the tops of coins with High Gloss coatings. Please support your local VFW. Thank you for your consideration.
