I would like to express my gratitude to my fellow bloggers friends, depankanta, whycollect and Dickson for correcting me. At first I thought that this is a strike through cloth error coin. But it seems my imagination dragged me too much.
This is actually a lamination error coin. Lamination error is categorized under Planchet Error/Defect. A lamination error occurs when the surface of the coin looks like it is being peeled off. It is also caused by impurities in the metal used in the blanking process or by some debris that was in the stamping dies.
About 20% of the area on reverse get affected by the lamination.
A lamination error coin is a random error. No two lamination error coins are exactly same.

At the first sight, I thought that this is a heavily stained coin. But upon close inspection, I suspect that this could be a strike through error coin, probably strike through a piece of cloth?
Strike through error coin happens when foreign object came into the striking chamber, hence become struck into along the coins. Even remnants of the foreign object, or the whole object itself, sometime can be found stuck inside the coin.
The weight of this coin is 5.59g, only 0.06g less than the supposed weight, 5.65g. Circulated coins are always having lower weight than the actual weight due to wear.
