I don't have any of these coins except a 10 kopiyok 1992, so I'm just reading and trying to translate from my 33rd ed. Krause. Here's my interpretation:
10 kopiyok1.1a: 5 dots, brass
1.1b: 5 dots, al-bronze
1.2: 6 dots, brass
I wasn't even aware that there were varieties listed for these coins until I saw this thread. I've just taken my 10k out, and it's got 5 dots, so it's 1.1a.
25 kopiyok2.1a: berries don't have little dots inside them, brass
2.1b: as above, but al-bronze
2.2: berries do have little dots inside them, brass
No, I don't know what these "dots" allegedly inside the berries of KM# 2.2 look like. I'd assume a small incuse hole, making the "berry" a fat o-shape.
50 kopiyokI don't have one of these coins to see for myself, but I
assume the edge has interrupted milling, like an Australian dollar coin or a 1 euro coin.
3.1: 5 dots, 16 grooves per reed section, brass
3.2: 4 dots, 7 grooves per reed section, brass
3.3a: 5 dots, x? grooves per reed section, brass
3.3b: as above, but al-bronze
I don't know the value of "x" in 3.3a and 3.3b above, but it's presumably not 16. Perhaps it even has a plain edge. Either that, or the "5 dots" in 3.1 is an error, and you only need to worry about counting grooves when there are 4 dots.

Now, brass and aluminium-bronze both look yellow-coloured, but in all cases, the dates for the different alloys don't overlap, so you determine which metal you've got just by looking at the date (unless you've got an XRF handy

)
