It probably would be a good time to assemble a full set, but there are a few of the liberty haves that are pretty expensive. It's possible to find 30 to 40 fine liberty halves for the same price as a fine 1921, or 1921-D liberty half dollar. I'm not going after a full set yet, but I might condider it if I came across those to key dates at a great price in the future.
The barbers are pretty cool, but a little too pricy for me to go after a full set. The ones that I bought were between 10 to 13 dollars each in good to very good condition. Those were common date, and some of them get very expensive.
Then again, sometimes a collection just starts itself when a lot of different dates show up on the same type of coin
