+1 I think a 609-card set would take a bit of time to assemble, unless you can find a large lot of commons on ebay or through the registry. Maybe some of the other folks who have built large sets can chime in.
I worked on that set for a couple of years buying all 9’s. Got up to 324/609 and gave up, had a good mix of high and low pop commons, high numbers, and stars. Still have the cards I owned listed on VCP, it’s up to $44k right now. Think they were around $37k when I sold 5 years ago
