Looks like a D8 dated 4430S, so a late build 68 hemi front carb. I quickly looked on FB at previous carbs, and mostly sets show up. That said Tom at rocket restorations out in Washington had a set clean cores with choke for sale at $2500.00. They were D8 dated automatic carbs that show to have sold.
Andrew Sonntag who goes by 938-DAN on here sold a set of restored Manual trans carbs by crossram connection for $3200.00 back in January of 2022. they show sold.
I mention that to hopefully give a ballpark value to a set of carbs, but the rear carb will always have the most value due to the choke set up. IMO the value of a 68 front carb in running condition would be in the $1000.00/$1200.00 range.
