Cah you help identify these coins?

Hello forum, I have recently found two very ancient looking coins in a relative's collection, and I have been wondering how old they might be or what their story is. Pictures are below, as far as I know these were found in the mid-southern region in Bulgaria quite some time ago. Thanks in advance for any assistance you can provide in identifying them!

Measure is in centemeters, both coins are pictured in both sides:

I think both of them are a Byzantine anonym follis. In this condition it's hard to tell, but they may be these two:
N#53012

N#77795

Look around in the cataloge, maybe there are closer examples: https://en.numista.com/catalogue/index.php?e=byzance&r=&st=1-2-79-80&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=&a=&dg=800-1200&i=&b=&m=&f=&t=&t2=&w=&mt=&u=&g=&se=&c=&wi=&sw=
