I'm not sure, but this looks like either a re-punched date or possible DDO? You can see the secondary loop of the 9 inside the loop (like an RPM) and remnants of the tail. Also looks like a possible lamination issue on both sides as well? Asking for a little help on this one. Thanks.
Nice looking coin, but I'm not seeing what you're seeing at all! I recently bought a Colombian coin as well! Here it is, it's an 1871 Gold dos pesos !
In pictures 3 & 4, you should see the upper loop of the 9 going through the open middle of the loop and the tail trailing below.
Looks like a repunched 9 to me as well. Colombian coins from this period are chock full of date varieties and errors.
Yes you're right, looks repunched. Slightly, but still repunched! Gold star for the day for @Double Die! j/k
