The reason that some cash management offices turned to the plastic sleeves several years ago was the belief that the decreased cost of the plastic sleeves would help with the bottom line. Several problems arose that brought many back to the paper roll. I will mention a few here.
Difficulty removing the sleeve. Many customers were have a grand time opening these. While more durable than paper, this aspect also made it more difficult to open without a blade to score the length of the sleeve.
Feed errors. The feed mechanisms for the plastic sleeves have a greater tendency to feed coins such that one or two end up sideways in the roll. Customers that have a thin margin have a bit of an issue when several rolls come up short 10% due to misfeeds.
Increased maintenance costs. This little item may have forced many cash management services to return to paper. Generally, the simpler the machine, the lower the repair and maintenance costs are. With many of the sleeve rolling machines vs. paper rolling machines this appears to be the case.
Just my opinion here, but if you want clear plastic sleeves just so you can edge check for silver, I think you are selling yourself short. I believe that learning to recognize errors and varieties can easily be more profitable than just pulling silver. Many who do it all, that is pull silver, errors, varieties, etc., have a far better cash flow than most who only pull silver.
Time for more coffee.
