As I said, you will never get everyone to agree. It is also said 'You cant fix stupid'. I also take issue with your assumption that every dug coin needs cleaned(rinsing the dirt off is not cleaning). Not every coin needs to look new and shiny and tarnish free. Hell I am only one forth the age of the coin and I can tell you I am no longer shiny or new....

I look my age and I've been detecting for over forty years and collecting longer than that. 200 year old plus coins are generally going to look their age. This lady has seen some life, she was not in 'grandma's underwear draw', she is still pretty. After rinsing after the dirt, what more needs done? you can see all the details. That is all that is required. Why does it need to be tarnish free and shiny?
The cleaning and not clean issue has been going on and discussed as has with 'it up to the individual' argument'... as well as 'I've cleaned' coins' argument as well as the dug and non-dug coin agreement.
I've yet seen anyone say you cant do with you finds as you choose, they only are offering the best advice as to preserve them.
It is not like someone like me or the others has something to gain by you cleaning or not cleaning the coins you dig up. I gain nothing whether you do or not.
They offer only the best current information by the leading experts in the field of numismatics only in the hope someone doesn't damage a coin.
There maybe people like you who feel that 'cleaning' somehow is okay. That is your right, however the vest majority in numismatics field don't feel that way.
