1961-D Nickel Error, Die Cracks And So Much More

The Barber half will probably be worth more than all the other coins combined. Age, 'S' mintmark, plus silver melt value.

Here is a PCGS help to grading. (Keep in mind that if the coin has issues, that will lower the grade a lot) But yours seem like there should not be any issues for your coin. Just a point I wanted to make to help new ones with their grading skills. A mild/med/large damaged area can turn a coin into a cull, regardless on how the coin wear will grade. Cleaning a coin will can also turn a coin into a cull coin, reducing the coins value up to 90% less than listed values. They turn into a problem coin that will be a hard sell to a seasoned collector. Newbies will jump for them, but then later that will regret they purchased the coin when they go to sell the coin.

I have a 1913s penny as well. No date but I zoomed with camera on my phone and can faintly see the s mintmark. Do you or someone you know have any expertise with them?

Not a penny sorry. Indian head type 1

When you post several coins you are getting as much of attention as a doctor determining what is wrong with a room full of people. A better effort will be spent on coin for coin views, of just one coin.
