completed listings

i sometimes look at these to gauge what things are selling for. I am seeing some with strike through and some without, both are sold (in green). Can anyone explain this?

strike out are 1s that finished early, I think (sold for a lower price, best offers maybe).

In advance search, search for sold rather than completed listings. Sold R the only listings worth researching.

thanks!
