I have a new coin and i need some help. The patina is falling off, you can see it on the lower right side. What should i do?
This is a very large coin over 1 inch. Can anyone help ID it.
Sorry about the poor pix, it's my first try.

I think your problem is bronze disease. You would need to boil it in a sesquicarbonate solution. There are a couple topics in this section you can find about the disease or just click on the words bronze disease.
All the best

It doesn't look like BD to me, just a soft and crumbly patina.
I think there's nothing you can do to clean it and if you remove the patina there'll be nothing left of the details.

I tend to agree with Areich with this one, although it is very hard to tell by the pics,

Removing the patina will,  in my opinion, wreck the coin, and   leave you with a pitted surface  with little on no detail.  There are also spots on the pics  that look like large pits ( below the surface of the coin ) and what seems like  " fragile edges " waitting to fall off

Soaking  would more than likely remove some of the patina, hummm 

Before I give advice on the cleaning,  I need to know what you use for magnification when cleaning, and also to see if you can post some more Pics  with a close-up of the obverse  (  if possible )

I don't think this coin is imposible to improve,  but just that it's going to require lots of patience so as not to do more damage than already exists

It does look like Domitian. That nose, only a mother could love.
I will try more pix soon, i have photoshop, hope that will help.
I use a magnifineglass nothing fancy.
I have tried to lightly scrape it with a craft knife to just clean the dirt off. Ren wax and that might do it.

just to be clear, I cant recomend R.wax,

1) dont have the coin in hand so its hard to judge  (and im not an expert Smiley )

2) r. wax in a ruins coin in some collectors opinions. Only used it a 4 coins myself.




EDIT: I baked my coin a lil before to make sure no moisture was on it.

Without the coins in hand,  the only thing I can think of would be soaks in DW  and washing soda , or  gringotts,  followed by brushing  with the Nick-a-brush. and repeat,  repeat  ..... 

The soft brass brushes available here at forvm.

http://www.forumancientcoins.com/catalog/roman-and-greek-coins.asp?param=0S681q00.jpg&vpar=1336&zpg=2502&fld=http://www.forumancientcoins.com/Coins/

I have used these brushes with good sucess on some coins. is a bit more agressive that a nylon brush,  but  wont damage the patina if used lightly.

I honestly don't think this will be a fast fix, nor will the coin ever be a FDC quality... and it will require lots of time and patience to get this coin to improve. but  it should be able to be improved on a bit

Finally, i have the rev at a stopping point.
I still can't find a good ID that matches the legend.
it seens like a BONVS EVENTVS. Maybe the legend is matched with some event?
Any insight would be much appreciated!!! Thanks!

Probably best to start a new thread in the id help section,
