What coins are these?

[ubersoldat]

Hello,

I would like to know if you could help me with coin identification. I believe the silver ones are from around XVII century (Livonia/Sweden/Baltic states), but don't know for sure. Any information would be appreciated.

Welcome Super Soldier to Treasure Net! The coins are out of my expertise, so I am of no help there. However, I would recommend placing them in a light bath of Acetone to arrest the verdigris aka verdi gris, rinse with water, pat dry then soak in Extra Virgin Olive Oil or Mineral Oil to loosen dirt, grime and corrosion on them as well as stabilize them from futher decay and damage. Once done, remove from the Oil, rinse and pat dry and more details will likely be visible.

The coin below the top left one appears (to these eyes) to be a medieval silver solidus from Riga (Livonia) during the period 1634-1654 (Christina); cataloged as KM#21.
Don..
PS: This coin has also been identified a a billion solidus from Riga under Swedish occupation 1653 (Christina reign). Actually, you can see the "5.3" in both the OP's coin and here: http://www.forumancientcoins.com/gallery/displayimage.php?album=1773&pos=7

Don you are a master of coin IDing.

 

[Mackaydon]

Here's a better view of what your top coin once looked like:

Thank you very much for accurate and quick answers. Do you have any ideas on the last one, the bronze or copper one.

 

[ubersoldat]

By the way huntsman53 I read that soaking a coin in Extra Virgin Olive Oil gives a thin protective layer but it also may end up with a dark stain on the coin. Is this true? And if it is, is it still worth doing so beacause of the protection?

 

[Mackaydon]

What is the diameter in mm of the last coin?
Don...

 

[Mackaydon]

The mark "S C" (Senatus Consulto) meaning "by decree of the Senate" indicated coinage authorized directly by the senate can be seen on the reverse side, on each side of the figure.

It seems like there are letters V and G on the top left.

Yes, Extra Virgin Olive Oil protects the coin when you leave some on it once the cleaning has been done and it can also darken a coin, especially when left soaking in it too long! While Mineral Oil has it's advantages of protecting coins from further environmental damage and will not darken them that I am aware of, it does not have the acid cleaning properties that Extra Virgin Olive Oil contains. One can always soak a Copper coin in the Extra Virgin Olive Oil for a short time, rinse with water, pat dry, then transfer the coin into a Mineral Oil bath/soak. Once a person is of the opinion that a coin's condition is not going to get better, no matter how much longer it soaks or is cleaned with a toothpick or green Rose Thorn, then just remove it from the Mineral Oil, rinse with water, pat dry and then place it in a protective holder such as a coin 2x2.

This may be the reverse; less sure of the obverse:
Rev: Aetemitas standing facing holding heads of Sun and Moon (RIC597a)
Obverse shown is SestertiiofMarcus Auirelius, Maximinus
Don.

 

[ubersoldat]

Thank You very much, it seems your guess is correct.
One more question for huntsman53. When you wrote "in a light acetone bath" by what proportions should I dilute the acetone (do I delute it with water?)? Also I've read that nail polish acetone is not suitable for this, is this correct? Should I go for a different kind of acetone?

 

[Mackaydon]

Another candidate for the bottom coin:

Antoninus Pius/Salus RIC 784C

No, you do not want to dilute the Acetone! Also, you do not want to use Nail Polish Remover (Acetone) as it has other chemicals added to it that can be harmful to the coin and/or will not do what you want accomplished. I purchase full strength Acetone from the Paint and Painting Supplies department at Lowe's. When I say light bath, I mean to only leave a coin in the Acetone for a very short period of time. I may place a coin in it for a minute or so and then light rub the verdigris (the green stuff) with my finger tip and might repeat once or twice more. You may dig a few coins with only light verdigris on them which may be easily removed but you will find many others that the verdigris is not so easily removed and often not at all. The main key is to basically stop the chemical reaction going on with the verdigris by killing or arresting it with the Acetone.

Sestertius ....(20-30g-35mm)...Dupondus (11-15g-29mm)...Ass...(9-12g-27mm.)

SS,
Based on the scale offered in post 13, I'm assuming it's a Sestertius.
