Rare Vintage Heavy Metal Chinese Zodiac Lunar Calendar Amulets For Sale

We have (20) of these Rare Vintage Heavy Metal Chinese Zodiac Lunar Calendar Amulets for sale and know little regarding them. I do know--there is the calendar with the Tiger, Rabbit, Dragon, Snake, Horse, Goat and Dog. The Rat, Ox, Monkey, Rooster, and Pig are missing. There are several other amulets with (I believe) Budda or others. Please enlarge and notice detail of each piece for your own clarification. This is not an item we would normally have available; however, did purchase at local sale and would love to sell. The price quoted of $300.00 of course is for all of the 20 listed. These are 2 inches x 4 inches and weigh a little over 1/4 of lb each. We prefer not to sell individually but move the entire lot. We welcome offers, of course. We do not live in an area where expertise in metals is common. We do not know if they are simply alloy with some silver or what they are made of. Our personal testings did not reveal. We will; however, continue to research for you.
