Help With ID Coins

So I can put them in destillated water and nothing bad will happen to them?
coz some people told me to not clean them at all, just keep them how they are now

Any way thats all for this good informations you gave, it means a lot to me
And ye in newbe here so any nots are welcomed. In a future I will post lees on 1 thread

Thanks again :)

Number 4 might be the winner of the whole lot. I missed the size (30mm) which almost certainly makes it a sestertius. I will stick to my 'guess' that it is 2nd century although it may be one of the Julia's of the family of Severus, which would make it early 3rd century. The condition it is in resembles an ancient coin "as found". Until it is carefully cleaned it is very difficult to judge what you might find. Could be a gem or it could be a dud. Based solely on the relief it seems to show I would expect to see something positive but only time will tell !!

Being new at this game I urge caution. A thousand years of crud does not come off in one day. Give this one at least a month in distilled water and brush gently with an old toothbrush. Then repeat !

Number one looks like it may have a hard green patina beneath the dirt. This is very desirable and care must be taken to not damage the underlying surface. If it is solid and intact over the whole surface it will help in the cleaning process. The patina can be very hard and resistant to any more aggressive brushing you may use later on. Always start gently until you can determine what is happening. Cleaning is good ....... Over cleaning is very bad and usually irreversible. Unless you have a thousand years to hang around waiting !

We can have a contest ....... Guess the mystery 'ruler' ! Without the weight it is a bit of a shot in the dark. But 30mm is pretty standard for mid 2nd century to early 3rd century. Most of my first century Sestertii are 32-3mm ...... Small difference but noticeable. Assuming the measurement is on target and the lack of a 'goiter' ! I wager my 'wurst' AE that it is female 2nd century.

If you decline the challenge .......

"I will taunt you a second time" !

I put them in destillated water, in couple days when they clean a bit, I will post last 2 coins.
