i actually have 4 of these, 2 of which i think are good, and 2 that are bad..
the information that i have says that the major things to look for are:
teardrop shape suspension ring on ribbon
"beveled" suspension ring on medal
stippling on medal
bottom loop of "8" slightly thinner at right.
are these the correct points to be looking for, and are there more things to watch out for?
i did a couple of pictures outside in natural light and my closeups indors.
