Pictures of the Coins are taken under the white flood light so some coins are more illuminated than the actual look of the coins. Also it may be impossible to show ALL the wear and tear, scratches and actual condition of the coins in the pictures. Pictures are the just closer representation of the actual look of the coins.
I have tried to explain the coins that are not certified and describe the condition of the coin, it is fully based on my opinion. I do not clean any of my coins, and I do not have time and enough resources to clean professionally. Most of the old coins that you buy may have passed through several hands over the years. So there is a chance many of the old coins may have got cleaned by old collectors, because the less aware about the importance of not cleaning coins. So some of the coins listed may be cleaned by previously owners , of its long history. All I can answer whether coin was cleaned or not based on my understanding on what I see. If I mention anything about the condition of any non-graded coin, is just my opinion only. If you have any questions, please ask me before buying it.
