Помогите перевести предложение. В частности "was used to back paper currency up" Another, more advanced example of commodity money is a precious metal like gold – which for centuries was used to back paper currency up until the 1970s. In the case of the American dollar, for example, this meant that foreign governments were able to take their dollars and exchange them at a specified rate for gold with the U.S. Federal Reserve.

'was used to back paper currency up'

'back (sth) up' means  to provide help or support for something.

for example,

Officials discussed the possibility of using military forces to back up the police.( в русском языке- поддержать или обеспечить поддержку)

В Вашем случае для валюты понятие 'back up'- support переводится как термин "обеспечивать", т.е. "золото, которое веками использовалось для того, чтобы обеспечивать стоимость бумажной валюты".
