from that video... These are my two hammered strike Philippine Silver Amulet.Namely "Un Peso Sagrado San Jose Verdadero" and "Luck Pocket Piece". It is said made of Mexican 8 reales Silver coin or a 1903 United States Philippines 1 Peso then hammered strike to make it an amulet. The year indicated on the amulet could not be correct but still it is made up of Silver. I saw the Un Peso Sacrado Verdadero selling on Ebay for $100 each but the Lucky pocket piece Amulet was nowhere to be found on the net.
I think if you hit it .it sounds like silver. made from Mexican 8 reals coin or a 1903 United States 1 peso. cool 1 you have. it looks like someone carried in their pocket their whole life for good luck ? If I were you I would not sell it. keep it for good luck.
I may be a little superstitious , but sometimes I believe in good luck and karma. If not to personal a question ? where did you get this coin/amulet ? My guess is the luck comes from when you carry it with you. I am not sure if that is correct or not ? maybe others on this CoinTalk might know more about it. I just did a very quick search of the words "Un Peso Sagrado Y Verdadero" on Google to research it. No that video is not mine.
good luck with your research. I must sleep now 4:03 am here in St. George, Utah USA. goodnight. zzzzzZZZZZzzzzzz sleeping now.

yours looks not only to be a match with the 1st photo but it looks like the exact same coin/amulet with the exact same markings and dents/scratches. wow what are the odds. I matched your photo with the coin/amulet in the first photo. they are the exact same coin/amulet. I would contact that guy in that website to let him know you found thee exact same coin/amulet. he might be able to tell you way more about it. Wow what a great story this would make. "Lost and Found Amulet". seems like good luck is already started for you.
