Both are probably genuine but I would be wary of the holed one more because it looks exactly the same as another famous 1830 PCGS MS62 which is kind of weird even the missing "M" is the same and the scratch or mark is also in the same position! Maybe a cast copy and also its holed? very strange. Could be genuine but would be cautious. The 1830 cuzco if you look in the old books shares the same numbers as others. A bolivian 1830 shares the exact same characteristic as the above cuzco. The cuzco is 100% genuine the holed one is questionable. The hole is possibly a ploy to make it look authentic.
