Pawnbrokers Sign  aka Garland triad, aka 1-2-3 sign

The pawnbrokers‘ symbol is three spheres suspended from a bar. The three sphere symbol is attributed to the Medici family of Florence, Italy, owing to its symbolic meaning of Lombard. This refers to the Italian region of Lombardy, where pawn shop banking originated under the name of Lombard banking.

“According to legend, a Medici employed by Charlemagne slew a giant using three bags of rocks. The three-ball symbol became the family crest. Since the Medicis were so successful in the financial, banking, other families also adopted the symbol. Throughout the Middle Ages, coats of arms bore three balls, orbs, plates, discs, coins and more as symbols of monetary success. The three-ball symbol became the family crest of the Medicis . Since the Medicis were so successful in the financial, banking, and money lending industries, other families also adopted the symbol.”
