I agree! XF
The patina is also very nice.

Yes XF!

The only problem concerning that coin is that... is not in my collection :)

Congratulations. Good coin!

thanks guys for the replies, this coin is in my swaplist

Those dark green spots on your coin are Verdigris (a form of corrosion that can appear on copper coins) and they will slowly eat your coin surface over time if left untreated. Acetone is usually used to remove it.

Based on that, I went to local chemist an hour ago and bought a small bottle. Is it something you have to wear gloves while using, and do you dip the coin in it or wipe it over, and afterwards do you wash it off?

To be honest I have never used it but I heard its one of the only methods that will dissolve fingerprints, sweat, oils... On a coins surface some have had sucess of removing the verdigris by letting the coin in it for half a day, then it needs to be thorougly rinsed with warm water. Thats how a friend of mine did it, but he also told me that it didnt remove the verdigris on all of his coins only some of them. Its pretty much considered by grading companies the only method of cleaning without the coin counting as cleaned after the process.

 Thanks - I will give it a go; never used it before which is why I asked questions - and why I only bought (£1.54 for 50ml) a small bottle. Hope to have some before and after pictures in a few days.  

Oh and i forgot to mention in numismatics it is mostly used to remove PVC color discoloration on coins. Apparently it is very effective at doing that.

Acetone is good at cleaning dirt and minor marks (like finger prints) from coins. I used it on Silver coins many times now and it does not affect the natural patina of the coin. You can dip the coin in Acetone for couple of hours too for better effect. It's not very effective on corrosion and oxidation specially on copper or cu-ni coins.

I use WD40 on copper or cu-ni coins with a earbud to remove oxidation and to prevent them from further corrosion. So far worked OK for me.

Acetone is all good, WD-40 is more
