Pictured below is a bronze follis of Anastasius, struck AD 498-518, Constantinople Mint, 5th Officina, 18.18 gm, 33 mm, 6h. Aside from some areas of encrustation it's not a bad looking coin. Pictured below is a gold solidus of Phocas, struck circa AD 607-609, Constantinople Mint, 5th Officina, 4.44 gm, 22 mm, 7h. The coin is in choice condition with a decent looking obverse, however, the reverse die looks like it was prepared by a drunk ! Pictured below is a Byzantine bronze Enkolpion, 9th-11th century, probably made in Constantinople, 110 mm long, 47.2 mm wide, 9.7 mm thick, weight 90.6 gm. The front side depicts Saint John the Apostle, and the back side depicts the Virgin Mary, both in the Orans posture. This Enkolpion is intact & in choice condition with a handsome patina. Of great importance, it hasn't been opened since ancient times to see the contents of the cross. Enkolpia are hollow reliquary cross pendants worn by Christians that became very popular after the Iconoclast controversy ended in AD 843. They usually contained relics associated with religious figures, saints, or important members of the clergy. Snippets of clothing, small coins, locks of hair, inscriptions on papyrus, & samples of soil from holy places have been found inside of Enkolpia. Some Enkolpia are said to contain slivers of wood from the True Cross ! These reliquaries were cast in two halves & hinged at the top & bottom with a movable hanger added to the top of the cross so they could be worn as pendants. They were often buried with the dead or kept in families & passed down to future generations. Pictured below is an Enkolpion that has been broken open at the bottom hinge to reveal the contents.

Nice scores, I like your Anastasius follis, which reminds me that I should get an upgrade! I want to like the encolpion but for obvious reasons they are a favorite of forgers and fake sellers so I hope you got it from a dealer of impeccable scruples, as its patina and style as well as the suspension loop style looks very similar to examples of fakes made and sold by Bulgarian/Serbian/Ukrainian/Russian fake sellers I've been keeping an eye on. A considerable majority of these that I've seen are fakes or suspicious so you need to be extremely careful with them. I hate to bring the cloud of doubt to your day but hate the idea of good folk possibly getting swindled far more, hopefully it's legit but I'd pick the brains of those with more experience with them, maybe @Ken Dorney can weigh in.
I did buy the Enkolpion from a reliable dealer with a money back guarantee. This isn't the 1st one I've acquired & I've seen my share of fakes over the years. I'm confident it's a good one & would be shocked if it wasn't.
