I've got a few of these, I'll post pictures when I get home. Some have easier to read years than others, it appears that your example is one of those harder to read years. If I had to guess I would say that your coin is from the 1960s or 70s, there were a lot of these kinds of errors produced then.
It looks to be a struck through Capped Die. You can grade any coin. For a mint error you also have to pay for a Attribution fee. It gets costly.
Weight? To tell between copper or zinc…but no to grading, not valuable enough to offset fees. @paddyman98 would have better advice as resident error guru. …imo…Spark edit to add: sorry, crossed with Ed’s post.
It's zinc. Based on the reverse design it was made between 1992 and 2008. http://www.varietyvista.com/09d WQ Vol 4 DC/01b LC Doubled Dies Vol 2/Memorial Reverse Design Varieties.htm
Struck through capped die. +1 You can see a wave through the face, typical from a capped die. Probably not worth slabbing but worth a flip in my opinion. See what they are fetching online. I see one site estimate $150 for an obverse cap but the brockage (your specimen) has to be worth much less. Fun find!
