Help With Large Cent

No. An environmentally damaged coin may have pits or "roughness" to it, but there are many, many large cents that do not. I would renew your search and find one of those!!

With so many available large cents out there, I would look for one without porosity (roughness) or any big rim bumps. Many cool coins can be had for under $20.

It is quite common for large cents to have rough surfaces, particularly for the early years.

The quality of the copper planchets the Mint received was often poor...sometimes the Mint even turned to scrap copper from sources like barrel staves. Remember too that copper is very reactive. More so than silver and gold. And large cents are 100% copper.

Even the leading third party grading companies are forgiving about a little environmental damage to early large certs. You'll see plenty of them in problem-free slabs.

Still, everyone prefers corrosion-free large cents and they can be located easily. The later years are much better and cheaper. If you are just looking for a type coin focus on the 1840's and 50's. If you must have something from the Mint's early years and do not have a lot of money to spend, expect some pitting and/or environmental damage.
Lance.

I could not remember the date. It was 1830's. It's graded xf by the coin shop and the details are exceptional but the fields are rough.

I wouldn't pull the trigger on this one.

Just use some patience, the right one will come along and you'll be so glad you waited.
Remember, there are literally thousands available, and quite a few of them are problem free.
