Botswana’s P10 banknote is being re-designed with polymer film to help improve the quality of the money. Facing public pressure to do something about the quality of the bills, the new P10 will have extra durability and will feature new anti-counterfeiting measures seen in British and Canadian currency. These new bills have a thin layer of varnish to increase the lifespan, while a clear polymer window shows a zebra when held up to light. The bank estimates that this should extend the lifespan by up to four times as long, which will help the low-denomination bill stay in circulation. The new P10 is scheduled to be rolled out in February of 2018.
