How to tell if coins have been cleaned.

[Coins Of the UK and US]

Hi everyone. I am trying to increase my expertise on coin collecting but I am unsure how to tell the difference between just high quality coins and cleaned coins.

If anyone can please help me with this, that would be greatly appreciated.

Thanks in advance, all the best, F Drummond.

Look for microscopic scratches (hairlines) (sometimes not so microscopic) that catch the light, or a "flat" look where the natural frosty luster is gone, losing the original "cartwheel" effect of an original coin. Comparing it to an uncleaned coin is often the best method. This is when a loupe and a strong light are useful. 

I don't mind gently cleaned coins - it can be done carefully with little to no damage. OTOH, sometimes for some coins I've happily bought more heavily cleaned ones because that brings the price down to a level my budget can afford. As an example I have a cleaned 1873 Bordeaux mint 5 Francs coin that is XF/AU details. Without cleaning, it goes for $125+; I got the cleaned one for $45 - less than melt. I'd love to find, for example, a cleaned but otherwise nice 1905 shilling because they tend to be quite expensive as _the_ key date in the 20th century. A cleaned one that is otherwise nice might have a price tag my budget allows more easily. 

Some collectors won't touch them at all but only really harsh cleaning with scratches and totally destroyed luster are the ones I avoid. 

Hope this helps.

This is unrelated but I am trying to add 2 photos on the forum but the forum says it takes up too much data and it won’t let me.

Could anyone please help me with this.

You need to ensure the photos total no more than 500Kb per post. You may need to acquire a suitable photo editor to achieve this - On Windows machines Photoscape, which is free, is a good option and the one I use.

Also, once you have posted a picture in a particular thread, the system remembers that and won't let you post another straight away. Simply come out of the thread and back in and it should then let you.

I have this very shiny 1937 USA buffalo Nickel. To me, it looks too shiny to not be cleaned.

Apologies for the bad photo, if I did the full image, it would have been too much data.

By the way, I use the Photo Manager app to keep the photos below 500KB.
