I have hosted a weekly 5-10 stud/8 home game for over 7 years now. Early on I had a similar problem with the bank being short. I could not figure out if I gave out too much change or if someone was bringing extra cheques. Most home game cheques are easy to obtain. As the house I was responsible for the short money. I would never dare to ask the other players to fix something that was my responsibilty.
Anyway, since then I bought custom chips from pokerchips.com . Sure they cost a lot, but are worth every penny, as I know no one else has the same set. I also know the exact amount of chips I have for sale in the game. Therefore, I know if any are missing or extras were snuck in. Secondly, I made a standard buy in (in my case $500)and have all my buy ins precounted in a chip case. This way I eliminate room for mistake in the flurry of all buy ins. Hope all of this was a help.
