For what it’s worth from this end of the country - not really collectible, unless it’s a niche fill for someone.
Local shop had a couple 1k lots of similar GI ammo in 20 round boxes from an estate, and 30-06 match in 20 round boxes for $20-25 a box - wasn’t moving last I looked.
The match ammo was dated by year, late 50s through the 60s.
They also had five of the Greek 30-06 ammo cans - those went fast at $250-ish.
You’re probably looking at about $1-$1.5 a round to move it - JMHO.
