Just joined after finding a small bag of older coins, many of them from other countries. What is the best way to find their worth or find someone I can trust to look them over. One man suggested I leave them with him for a week, but I did not feel comfortable doing that. One is 1960 second queen Elizabeth Hong Kong 1960 silver dollar! One looks to be a penny, copper, but much smaller. I think it says Gusta Adolfi with some kind of crown and a small number one in the center? Have a couple of what I think are Greek bills also? Thanks
