Sobre l'autenticitat del segell de Mossé ben Nahman de Girona trobat a la plana d'Acre

On the authenticity of RaMBaN?s seal
found in the Plain of Acre

The seal of Nahmanides was fortuitously found in 1972 at ground level in
the Plain of Acre As doubts were cast about its authenticity, the authors decided
to submit it to an X-ray fluorescence comparative test in order to ascertain
the composition of the copper of which it is made. The comparison was made
with three Mameluk coins of the second half of the thirteenth century, that is
to say, contemporaneous with Nahmanides? stay in the Land of Israel, and results
showed a great similarity. Therefore, it is highly probable that the seal is
authentic.
