Hello! Dear Numista colleagues,today I submit to you & your knowledge 2 type silver coins:
1) 5000 dinars AH1324 (1906) from Iran/Persia [Numista no.29123 ; KM981] with a catalogue weight of 23.02g.
2) 50 sen Meiji era-year 9! from Japan [Numista no.14249] with a catalogue weight of 13.48g.
Is someone of you who saw ''in nature'' a piece of both these coins? They both are rare type or date coins,with very low mintage records!
The question is: How much less than its given weight may have a piece of a somehow circulated coin as to be genuine/real ?!
Please keep in mind that at least the first Iranian coin was not an usual circulating type but was minted more as a gift from the Shah for his anniversary. The 23.02g. is known to be mostly a weight for other circulation types of the 5000 dinars denomination.
Thanks for your experienced opinions!
P.S.: I asked for how much less can a coin have, upon its catalogue weight,as to be still considered a genuine coin?! But,same question for the case it has a weight above its catalogue weight,how much such a ''tolerance'' should be???
Or ''tolerance'' for original mint strikes is not allowed even in special cases(old coins,low mintage records,special strikes,posible mint errors …)?!
