Just bought a lot of 15 Medieval coins. They look pretty real to me.  |

Off hand, it looks like one of the Spanish lots you can pick up pretty inexpensively.

Should I clean them or is that green corrosion part of the patina?

Chuck them into a small jar of olive oil, and leave them for 6 months. That does the trick for the preservation of ancient coins!

The larger one near the top with the shield on it will be a later-period debased-silver Hunarian denar. Not sure about any of the rest.

... or longer. Depends on how patient you are.

How do I spot silver in these coins? I heard you can't soak silver coins in olive oil.

UPDATE GUYS! Got the coins! They're really small. So should I soak them in olive oil?  |

Anyone can prove these methods of cleaning? Quote:
1. Soak the coins in distilled water and then put them in the freezer. The water will have gotten into the dirt and the ice crystals expand and break the dirt apart. Several repetitions will be needed to completely remove the dirt; however, it does not damage the coin.
2. Spread a layer of Elmers white glue over the coin with the coin laying on a piece of wax paper. Let the glue dry and then pull it off the coin. Again, a layer of dirt will be pulled from the coin without damaging it. It will require several tries to clean it completely. |

The ice cube method does work and will be gentle to the coins. I am not really sure about the Elmer's glue method though but it would probably not damage the coins either. If it was harmful, little Gary Glue Eater probably would have never survived the second grade  I would recommend sticking with freezing just to be safe. Once the bulk of the surface gunk is removed, you can proceed with a long term olive oil soak to finish the job. |

But wouldn't olive oil make the coins a lot darker?

Well, the distilled water trick didn't work. Soaking a couple of low grade ones in olive oil right now. Thinking of buying the ultrasonic cleaner.

If you rush it, you'll ruin it.
Be careful with your cleaning attempts or you might just wind up with a bunch of pitted slugs. You have to know when enough is enough. You want to get to a point where there is some detail but not down to bare metal where it looks like crap.
