For a more accurate photo, turn off the overhead light and just open a window. Any kind of artificial light nearby will reflect off and give a gold tint to the coin. The natural light will show the silver color instead of a golden one.
Anyway, cool coins!
Thanks for the tips I also have a light boot that I'm going to try on future coins but unfortunately most of my coins are not on hand so I don't really feel like getting them to retake pictures but moving forward the new pictures should be better
