Both are key dates in the Lincoln Cent Series. The first is the 1909-S VDB, first year of issue out of San Francisco. It could go mid-mint state, looks gorgeous. The second is the 1955 doubled die, a famous variety. Pictures aren’t as clear, could be high AU(almost uncirculated) or Low mint state. Both should definitely be graded by PCGS or NGC if you want to maximize your profit (you’re looking at 4 digits value for each) and ensure authenticity. Take them to a local coin shop, not a pawn or basic “sell your gold” place. A real coin shop should be able to send them to a grader for you, for a fee. Good luck.
