'83 And '59d Penny Errors?

The date in the '83 then on the '59 d it's the second 9 most of it is missing then the word trust most of the letters are shrunk or not there at all and the B in liberty is hard to see but the top is crushed or missing?

my guess is a Grease Filled Die caused the missing parts of the design for the 9 in 1959 and the 9 in 1983 was probably damage from a rolling machine

The 1983 looks like it took a hit on the west side of the 9. I wondered about the Rolling Machine Damage, but looked at a normal 1983 cent and the tail sweeps normally on the tail like that. Usually if it is parallel to the rim, it is coin wrapper damage. But the west side of the 9 is altered from what it was when it was struck.

I agree on the rest being a struck through error. (grease)

As for the gas bubbles, this is a zinc cent (1983) so the zinc and plating aren't in harmony with each other. I see alot of that within the zinc cents and I steer away from zinc cents. It they have a tendancy to rot, I for one am not willing to collect nor sell something that costs a "pretty penny" only to see if slowly disentegrate over time. Its copper cents for me !

SPEAKING of copper - the 1959-D you have is difficult to see. Here is what I suggest you try if the devices you use to shoot pictures has it. Look on the camera section of the device and see if it has a close up mode, or a MACRO mode. There is usually a flower associated with the setting. If it has a MACRO or close up mode, try that. It will allow you to take better close up pictures. If you use a zoom, try not to zoom in any closer than 2.0x times. It will keep the image from becoming blurry.

If you use flash or another source of light and it appears too bright, simply place a piece of sheer cloth or soething else over the light to temporarily soften, or diffuse the light. I have seen a few people use table lamps and drape a light colored shirt over it, I have seen people take coins outside and use the natural light (not directly in the sun) to take pictures as well. Lighting can be some of the most difficult things to master in taking pictures of the coins.

On the 1959-D, the coin either took damage, or, its possible the coin wasn't struck right. I cannot tell if the word TRUST is miniturized, or if there was a coin counter or roller damage. The coin can get stuck in a metal coin counter and take some serious damage in some spots. For coin counting damage, look for damage at the same distance away from the rim. You mentioned the "9" may have some issues, so if you spin the coin around, to might see very slight evidence of the coin having that same type damage in in other spots on the coin.

As a Matter of fact...take a look at the LIBERTY side near the rim of the 1959-D , see that almost halo looking stripe there? In the pictures it appears to be either a coin counter damage or "crimper" that is inserted into an open roll of pennies and then ins rapidly twisted to seal the end of the roll. In this case, it was done quite strongly, and this is the typical result.

Again, its difficult to see in the pictures. Don't get frustrated with taking pictures of coins. I have been taking pictures of coins for decades, and each coin is different. Sometimes a good set of pictures can take quite some time.
