1909 1 Peso Freak Coin or Fake ?

In the last Days i checked the coins what i get on the last two month and i found an 1909 Peso witch i like to show here. Maybe one of the Forum Member has an Idea what it is. A real low quality fake or printed on the wrong coin.

I put some more Pictures in high resolution in to the web so it is maybe more easy

The same Picture like before but in high Resolution

The wight of the coin is arround 19.6 gramm.

do you have a clear picture of the front and back of the coin?

the second picture is hi-res but the bottom part of the coin where the date should be cannot be seen. But looking at the pictures you posted, it doesn't seem fake to me. Based on the pictures, 19.6 grams i think should be just right for a coin of this condition

looks like it's a sea-salvaged coin (dumped into the sea during WWII to keep it away from the japanese and later recovered after the war) sea water corrodes silver. that should explain why it is slightly lighter and why it looks rough.
