Ancient silver coin? What is it?? [Resolvido]

I cannot find this anywhere!

 On second image I see LIVON so in Search I entered  *LIVON*  and there are 28 results. Need to know the size as well (that applies to anyone asking for identification!).

 On the first side I also see TINA D G so yours may be this one from that list ...

1 Solidus - Christina
Livonia  1645-1654  Diameter 15 mm  KM# 2

Obverse: Crowned C with Vasa's arms (wheat bundle) within inner circle
Lettering: CHRISTINA D G D R S

Reverse: Ornaments, a shield with the coat of arms of Livonia
Lettering: SOLIDUS LIVONIA (+year)

 Must be Christina (the 'girl king') from Livonia (in Sweden), especially with the big C monogram below a crown on first image. Shame as your second image shows it was stamped off-centre so some lettering or maybe date missing.
 I copied and rotated to compare with that page I found and not sure if it is an exact match, as what is in the centre of the second image does not quite look the same.





 The images on the right are taken from this listing below, and are the nearest I could find ...

and notice the 1650 date is just 50 on there, and shows where to look to see if the date can be found on yours. Luckily, in a way, the SOLIDVS part is broken off and only VS remains, but the date should still be there top left.

'At the age of six she succeeded her father on the throne upon his death at the Battle of Lützen, but didn't begin ruling until she reached the age of 18.'
