Vinegar contains a few percent of acetic acid. What you did was form iron acetate. As most know, acid is extremely damaging to coins. EDTA is a...
Welcome to CT! :)
You need to get in closer, you're not meeting the size requirement because after you crop you've cut away too many pixels. I use an old Canon...
Looks like just another method of separating you from your REAL cash.
No fear, it's fairly volatile and it will certainly be completely vaporized when the grill is heated. What you don't want is to get in on your...
It's good you came here to defend yourself. As an ebay seller myself, I understand your frustration. Did she leave negative feedback before...

Nice cracked skull!
I've had this happen a couple times, both times acetone kind of hazed the surface. I ran the coins though water and xylene after the acetone, then...
