The '80 is a woody. Improperly mixed alloy. The '65 is pretty well beat up, but looks like a lamination or struck through.
They don't have a lot of value, typically. The color of yours seems off but it's hard to tell from the pics. Usually the coin is a darker color and the woodgrain look is lighter and splotchy. Your coin has even stripes that are darker than the coin, looks like. That may be toning or something other than a planchet issue, or it could be original to the piece. Although there's several different types, normally a "woody" would look more like this...
Dont take this the wrong way, but I love having round, hard things in my pockets with heads on em after leaving the coin shop.
These 80's woodies are fairly common, more so with the one-sided type. IMO, it is not caused by a poorly mixed alloy because the appearance is quite different from the wheat cent woodies. The theory I've tossed about for years with these modern woodies is that the stripes are caused by impurities on the planchet sheet rollers which get pressed into the sheets before they cut them out. You can't see the stripes right after minting however those areas tone differently causing them to appear later in the coins life.
