Hell of a haul brother !! The bottom 10oz Engel is rare bar. Off the top of my head I want to say it is a 500 mintage ingot. Your example has larger spacking between the hallmark and weight/purity. Look it up on Allengelhard.com. Might be some comp sales there too. I have seen a few sell in the $500 range. Very nice find! JM 10s are great! The other 2 are common Canadian 10oz pours. The lower example seems to have a lower more desirable serial number. 🔥🔥
