Coin Quality - Rarely Good

[DeepThought]

I had a couple of hours free after work & decided to visit a local tots lot & walked away with a little over $1 in change. All the coins I've collected so far show heavy deterioration. Only those minted in the past several years have any real face quality...hard to even read the dates.. However I always see where folks have dug up mint barber coins, etc. - something unique to soil conditions? What does our coins look like when you dig them up?

newer coins of clad layers eat away due to dissimilar metals , and yes some soils will damage coins faster than others, older coin of copper will most likly be green patina aka corroison when cleaned may or may not have pitting silver coins mostly come out of the ground as if they where just dropped all though some may be darker dur to tarnsih or patina , salt water is some thing i can not comment on as i have no experience with it ,, nickle coins may be dark almost black when they come out some if older like a buffalo it may come out light greenish patina , not to sure about war nicks with silver , but most nicks come out dark and pitted , helps this helps other may have a better way of answering

Salt water is hard on all metals except gold. The amount and type of mineralization in soils will effects certain metals differently. Fertilizers can be hard on coins too.
