Hi, I have a
Philippines 1906S 1 peso Authenticated by NGC for surface hairlines in AU Details. But as I carefully check the coin, it has the
MD - Mechanical Doubling or MDD - Mechanical Doubling Damage of the Letter "
U,N,I,T,E " of the word United and "
E,R,I,C,A " of the word America and the number "
1906 " including the "
s" mint mark in reverse has the MD (
Mechanical Doubling) and its very visible using 30x lens. Is the Error MD (
Mechanical Doubling) can affect the value of my coin? thanks !
