Ok so i tried em at one location where other business' were wiping out my quarters every week. I gave it a year. I only bought $8000 in dollar coins in a years time. I never deposited dollar coins and I still have $976 in dollar coins so $7000 in dollar coin walked away and never came back. Too many people asked questions. The customers didnt know what they were and didnt spend them. My guess is they took them home to their grandson or something. I can say they were alot easier to handle than quarters but it was very discouraging to open the vaults and there was almost nothing there. Id have to look at my notes to get a percentage but there were always more quarters in there than dollar coins. That means that the customers had to bring the quarters themselves. It was close to 40% dollar coins and 60% quarters. Bills and cards both went up. Overall my year over year was $5000 less but some of that could be the timing on deposits. I dont blame it all on the dollar coins but there was definitely no increase in revenue. I went back to quarters and the vaults were back to normal on the first collection. Within 2 weeks they were wiping out my quarters again. I still try to stop it when i see it but im picking my battles now.
