Pound for one Allende with a line crossed through right money (11)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

L (abbreviation for a pound sterling, from Latin libra ) + EG (for one = for example), then AL [l] ENDE (presumably the novelist Isabel Allende) with the second L “crossed through” to make it into a T , then R (abbreviation for right). Legal tender = a form of money that can legally be offered and accepted as currency.
