Added another update to my Family History Type Set by picking up two more coins today, a 1/2 kopek & 2 kopek coin each for about a $1.
I'm pretty sure that these are the last of the ultra cheap coins. Another problem I'm running into seems to be availability here in the States. Looks like the last 7 coins will be a little tough in the date ranges I need but that's what makes this fun :))))
update to what I need (9/22)
What I still need: 1/4, & 25 kopek coins, and a 1/2 & 1 rouble coins.
