I've only done the dollar coin thing a couple of times. However, I try to spend/ distribute as well as bring some to the bank. In NY many gas stations now charge two prices: credit and cash which is usually 5-10 cents cheaper per gallon. I figured to get the cheaper price why not use coins! I also use coins to buy from street vendors and other cash only businesses. Why not distribute some coins when cash is the only option for a purchase.
