    If its vitreous enamel i.e. glass then unless it is loose and you can pick it out then the only way I know is to soak it in hydrofluoric acid but I would not go anywhere near that stuff, its highly dangerous. It may be possible to break it by tapping it and then picking out the pieces but depends on how well it was applied in the first place.

    If its the resin type of enamel, I have burned it out in the past but its very sticky and makes a mess.

    I would leave it alone. For me toning is a natural occurring effect and I rather like it. I don't think any capsule or container that we put a coin into will ever stop it, some might slow it down if they are sealed in someway such as the CGS type but in the end I reckon even they will let something through.

    If your coins are toning then the likelihood is that it will come back again and at some point you may damage the coin when you wipe it.

    How do you store your proofs, are they in a cupboard or safe and what is the temperature and humidity like? I would imagine changes in these and possible exposure to light would have some effect on how quickly toning occurs.

    I have used an ultrasonic on individual coins, I make up a jig using a piece of plastic coated wire and gently wrap this around the coin so that it is in minimal contact with the edges. 

    I then get the ultrasonic as hot as I can and dangle the coin in the liquid. I do not let the coin come into contact with the machine to prevent any rubbing to the coin.

    I have not used acetone just soapy water. It shifts the dirt but will not remove verdigris unless it is a loose spot.

    i do not rub the coin with anything I just let the ultrasonic remove loose material. I then soak the coin in acetone and let it air dry.

    I have only used this method on circulated coins that have obvious grease and dirt problems.

    Hi WildCamper,

    if I can offer a piece of advice not on the coin but on the background that you place your coin on to photograph it. It looks like you have placed it on a hard kitchen worktop? 

    If you accidentally drop the coin you may damage it, also some coins have high spots that are higher than the rim edge so will be touching the hard surface. Again you could damage the coin especially if you drop or drag it across the surface.

    if you look at most of the photos on this site the coins are placed on a soft material to protect them.

    All the best

    Looks in good condition to me. Nice detail in the hair, ribbon etc. I will take a punt and say EF but maybe better I would rather be conservative on the grade. As to value I will let more experienced people comment on that.

    What condition is the other side like?
