In Person Observation:

- The Coin has a thin planchet and darker color character. The obverse has a deepening on the cross from a strong striking of the mint. The reverse bears a visible shield with slight fading on the exterior. 
- Less than 4% of the coins recovered from Atocha we struck at the Mexico City mint, as most were minted in Potosi, Peru (Modern-Day Bolivia), where most of the Spanish crown's silver shipped through the Spanish Main landed.
- 4 Reale Denomination growing increasingly rare: Most of the coins on board the Atocha were of the 8 Reale denomination. Due to their smaller size, 2 and 4 Reale coins didn't survive the shipwreck as well as the larger 8 Reale coins did.
