wheezydog - I'm not a vinegar guy - I use a bulk chemical used in municipal water treatment, so I can't give you much advice on vinegar. Yes...finding an 18/7-D overdate in just 1 roll of no dates would be insanely lucky! I have found 10 of them over the course of the last 5 years and I have probably sifted through over 25,000 MINT MARKED nickels in that time...so if you find one in your roll of 40....the Buffalo nickel gods must like you a lot!
