How pure is the gold Solidus coin?

Anyone happen to know the gold purity of these gold Solidus coins?

This is mine:

I’m just curious if anyone happens to know the purity because it would be interesting to know how high gold could be refined at that time.

I’m hoping it’s at least as pure as the older Roman aureus coin was. Even if it is lighter.

I am not, repeat NOT, an expert in this area. However, I did find this:

"The gold solidus was the workhorse of the Byzantine Empire for centuries, and was generally struck from about 95.8 percent fine gold, the highest purity available in refining at the time."

Thanks! Wow 95.8% is like 23K that’s pretty good!

It’s lower than a Roman aureus but It’s higher than an American Gold Eagle or any pre-1933 American gold coinage intended for circulation like the Saint Gaudens Double Eagle. ^_^
