The first two look to be some Arabic numbers/letters, similar to those I've seen before on Egyptian gold. The third looks to be a human head inside of a border, but most of the detail has been rubbed off of it and after reading for a while could not put it to a country. I was hoping someone else would have more knowledge on or could identify any of the hallmarks. I would greatly appreciate any information. Thank you!
