I am not a "Collector" just interested in old coins. A friend who lightly dabbles in coins, asked me help identify a coin and its markings. I started looking thru coin references. I have been unable to locate the marking in references and on web sites.
I found a coin very simular coin on the web, but "close only counts in horse-shoes".
Any assistance would be appreciated. I hope I am using the correct terminology in my description of the coin.
Am told coin is "Spanish Reales". Some references use the terms
"Portrait", "Modified Pillar" or "Milled Bust" design.
{the * = dot}
Obverse: CAROLUS (Bust facing Right) III * DEI * G * 1778 *
Interp. as: [ Charles III by the Grace of God 1778 ] ?
The biggest noticeable difference is the "III" over the bridge
of the nose instead of behind the crown of the head as shown in
most references of 1778 coins. I have also read some about the
importance of the "C" in Carolus and where the printing starts
in relation to it's position of the shoulder and hair/pony/tail.
( I presume to help id a forgery ? )
Reverse: *HISPAN*ET IND*REX*Cº[* dot under the little o]G*R*G*
Interp as: [King of Spain and the Indies * mint mark *
denomination * and the assayer initials ] ?
Unable to identify the mint mark {Co} in any references;
determine the coin denomination {G}, and the assayer
marks {R*G}.
The "Pillars of Hercules" with the Spanish Shield and
Crown are also on reverse. Motto on the banners on the
pillars bear PLUS VLTR [abbrev for Plus Ultra (More Beyond)].
Also the outer edge around the coin has the alternating
O and rectangle design.
Well....all this is what I THINK I KNOW...
Any information or references,would be appreciated... Thanks...wm
