[Avodah] money and halakhah

[Marty Bluke]

The Aruch Hashulchan Choshen Mishpat Siman 66 Sif 9 writes:
"Sh'taros shel melucha hayotzim bamedina k'matbeyos kesef v'zahav,
yesh lahem kol din matbeya"

My translation:
Paper money issued by the government that is accepted like gold and
silver coins is considered money for all halachic purposes"

Tomorrow morning I will find the Chazon Ish and Chasam Sofer.
