I tested The pendent object with a HCl test and it came back at 80-90% Silver (Ag), but it could be a false positive. I also ran a density test on the object which resulted in 10.501 grams per cubic centimeter (the density of silver). The density of Lead (Pb) is 11.342 grams per cubic centimeter, so it very close. It has a specific gravity of 8.771. And a streak test came back grey.
As for the card shaped object it is metal, not sure what kind yet. If you examine it closely you will see that it actually 3 separate pieces that were "soldered" together.
