Wasn't Marcasite Jewelry popular during the late Victorian Period around the Turn of the Century? The style of this earring looks modern to me and not Victorian, but it is STERLING so that's a plus! Breezie
I personally never wipe silver coins. If you look at the picture you can see the scratches. I sometimes carry a bottle of water and drop them in it or i just put them in my pouch and bring them home and rinse them off. If that would have been a $1000 dollar coin you would have wiped off about $500 in my opinion.
I have done it to many years ago. If its a key date coin you would have lost value. After i rinse and see its a common coin with little value i sometimes rinse it and take some baking soda and put it on it when its still wet and rub it. It makes it shine like new. NEVER DO THIS WITH A COIN OF ANY VALUE. There is probably a better way under the cleaning forum. I seen your location from your aviator your up there where your going to find some old silver if you haven't already. Just dint want to see them early 1800's coins with them scratches across the date. So please say no to the rub. 8)
My name is Garabaldi and I am a silver rubber!!
I have found a couple of old silvers, but mostly musket balls and buttons.
I often wonder if my Whites M6 is the reason I am not finding more deep silver. I read on here that the minelab and some other name finds deep silver.
Are you finding deep buttons and musket balls? If you are you will find silver at least that deep. Your m6 looks like a good machine to me i have a old eagle spectrum. It's about 14 years old the deepest coin i have dug with it was a barber dime at 9 in's it was ringing loud and clear. Good luck and keep swinging
