I would ask for help and assessment. This type of coin is for their variability too complicated. I don't want them to stay on the pile of unspecified. And yes, first of all, I always do a careful search- however, consultation is really needed here.
I will give my own view and discovery here and may differ from reality. I followed using this search engine -
http://www.silver-copeck.ru/211.html
they are Russian silver wire coins:
a, 0,46 g, 14,03x10,2 mm , Михаил Федорович ,Jaroslavl -790 E

I think it's this type:
b, 0,46 g, 15,1x8,8 mm , Also - Michail ( Михаил Федорович ) No. 473 ,y.1626-1635


c, 0,25g , ( This is strange when everyone has an accurate weight) 13,4x7,8 mm, IVAN III. Moscow ( Zaitsev -13.1, Guten -498 ?)


d, 0,43g , 13,5x 9,2 mm, Michail ( Михаил Федорович ) (number 523 ?) y. 1636-1645


e,0,42g, 11,8x 9,3 mm , probably also Michail , but I didn't find him any closer ?

f, 0,46 g, 13,5x8,1 mm , Michail ( Михаил Федорович ) ,I think but I'm just guessing No.510 y.1636-1645

I know it is a lot, but I'm sorry about everything from one workshop.
Any help is welcome
Ivan
