Planchette Errors? 1935 And 19?

Severe damage, soaked in acid perhaps? Poor coin.

Second coin looks like moderate damage.

We really appreciate it when the one coin per thread is used, but since you have provided both of them here. I'll go ahead and comment on them.

The first coin has been deformed and destroyed some from some unknown sort of acid which has completely destroyed it. Certainly no premium, and you may not be able to convince someone to give you face value for the coin.

The second cent just has damage that has ruined any value the coin may have had. Both coins were damaged post mint. These issues could simply not have occurred at the mint, as there is nothing in the minting process that would cause this damage. Just to confirm, both coins suffer from PMD.

I realise you are new here and might have presented what you thought were rare treasures. I wish I had better news for you. I would encourage you to keep searching. Another CCF member here just found a very uncommon but very valuable cent coin by just looking through his collection! Lots of good coins still exist "in the wild" as we call normal circulation. And as always, we'll be here to answer any questions you may have along the way. Good luck!

to the CCF!

The 1964 cent you posted was struck onto another coin from
India. Coins have been struck with all sorts of things in them such as grease, hair, nails, staples, and wires in the past

It's not the same pattern, but here's a jaw of a vise. You can see what would happen if it wasn't fully tightened.
