5 Vintage Lapel Pins American Flag NRA GM Michigan Sheriff Gold Tone

Five vintage gold tone, lapel pins with backs on all of them. The theme is patriotic, law-enforcement, NRA and Michigan Detroit automotive related. They include two different size American flag, lapel pins, an NRA, millennium, endowment, member pin, Michigan, sheriff pin, and a GM anniversary pin with three stones in them, two are red and I believe they are authentic ruby and one looks like a Rhinestone or diamond chip. They are tiny and I do think they are authentic stones, but the value would be very small. Two of the pins are stamped on the back. See photos for details.
