Cud or other error

The
"1" in 1958 appears to be a double strike, but I am not an expert.

Hi there! Welcome aboard!
The lump on the 1 is the result of a die chip. Relatively common on cents of the 1950's. I suspect that their die steel was a little too brittle.
The doubling on the right side of the 1, which by coincidence happens to include the area of the die chip, as well as the inside of the 9, is what is commonly called "machine doubling" or "strike doubling." During the strike and immediately after, parts of the raised area of the new strike bumped up against the edge of the die that had the characters incused into it.
This can happen at random on the coin, but it is most noticeable on the date as the characters of the date have steep sides to them and any sideways shimmy in the die as it is coming off the coin can bump up against the coin.
Unfortunately neither the die chip nor the machine doubling adds any value to the coin.
