Following the hearing, Lesley Thomson, area procurator fiscal for Glasgow, warned dealing in counterfeit currency was "not a victimless crime".
She said: "It can cause hardship and misery, particularly in difficult financial times.
"It is our duty to ensure that no one trying to profit from crime should succeed.
"We are determined to pursue any financial benefits gained from illegal activity."
