Il est très difficile de dater ces monnaies unifaces de billon. Certains considèrent qu'elles ont été frappées durant la période de domination thaï entre 1600 et 1870. Plus le taux d'argent serait élevé plus ancienne serait la monnaie. D'autres mentionnent la période 1847 - 1860.

K11 Hamsa Pe or Praq Pey Crude Hamsa left with crest, vine, and tail feathers as detached elements around. Chinese Ji (luck) in box above. From style and silvering, varieties with one or two dots above upper tail feathers and five horizontal dashes behind appear to be earlier than the variety with no dots above, and four dots behind. Local name "Praq Pey." Issued 1850-80 (Panish) or 1870+ (Cribb). K11a = one dot above, 5 dashes behind; K11b = 2 dots above, 5 dashes behind; K11c = No dot above, 5 dots behind; K11 = my choice Each crude VF-EF, maybe traces of silvering $4.00
