"Cookie" Coins
I have wanted to get more involved in beach hunting and have the proper equipment standing by for better weather.? Meanwhile I have been hitting the dry areas of a couple of beaches on a regular basis trying to gain some experience.The lake I have concentrated on has a very high salinity content due to the fact that it's source runs through the Great Salt Plains in western OKlahoma.? Therefore, I am finding many "cookie" coins just like you would find at the seaside beaches.? Most of them are pennies.? I can tell they are pennies by size and color and sometimes I can barely make out one or two of the features on the face of the coin. However, I have found a few clad quarters, dimes and nickels that are hardly recognizable.? A very hard crusty build up forms on the coins which I thought may just be salt residue, but they don't have a salty taste when you put your tongue to them.? Instead of eating up a zinc penny like normal soil conditions, it seems to form a hard cover that actually seals the coin inside.? On a penny, it actually eats into the surface and will destroy the coin if scraped off.? ?On the other clad coins you can scrape most of it off with a sharp edged of a knife without doing much damage to the coin.? I know it's some sort of corrosion, but does anyone know exactly what it is?? MONTY
