A word of advice. (I know I'm going to catch it for this!) If the payroll is from the period after paper money was introduced and before the invention of plastic, It isn't there.
Army's did not carry chest's of gold around enemy territory in the 1700's and 1800's any more than they do today. I wish they did, but they didn't. Chests of looted property are a different matter. Copper and silver are a maybe.
Think about it. If you wouldn't carry a chest of money down the streets of New York or Atlanta in peacetime, Why would Cornwallis or Bobby Lee? Even George Washington and US Grant were paid with paper. Outside the weight of carrying hard currency, No country risked furnishing its enemy with the finances to defeat it. I truly wish it were otherwise. (Believe me, I wish it were.) Every state in the US has tales of lost payrolls and supposedly Napoleon left gold laying around Europe by the truckload.
That said, don't let a naysayer steer you away if you have good information. But use common sense about investing your time and money.
PLEASE prove me wrong.
