Doubling on 8 and 9 on both coins

It isn't a doubled die, but is strike doubling - looks like from die deterioration. Pretty interesting looking, but not something that is worth a premium.

It is indeed die erosion doubling, aka die abrasion doubling. This is extremely common for any coin type struck on plated planchets, such as the 1943 cents and those of 1982 to date.

Can you explain why it is more common on plated coins? (Or link to an article, if you have already explained it somewhere)

The plating is very thin (except on proofs, where it is doubled), and the deformation which occurs during striking can partially spread the plating away from the core metal. Each year NGC receives 100 or more 1943-D and 1943-S steel cents that are submitted as doubled-die-obverse varieties, when in reality the distortion of the mintmark is due to such separation at striking.
