Welcome to the forum!  Your quarter has been damaged by heat, may have been through a fire.

It can't be an occulated gas bubble as the quarter is clad.   

iItis heat damage sometimes known as a Campfire Coin. Keep it if you like but it has no value above 25 cents

   Welcome to the NGC chat board.  

  The error type to which you referred is an occluded gas bubble and is not known to occur on clad coins. See https://www.error-ref.com/gas-bubbles/, which states, "While gas bubbles are sometimes seen on clad coins, these always turn out to have been caused by heat applied externally outside the Mint." 

  The 1984-P quarter has extensive pitting due to the heat damage, as well as circulation wear, which are likely the cause of its being slightly underweight. The official weight of a copper nickel clad quarter is 5.67 grams, with a tolerance of plus or minus 0.227 gram, so the coin could have weighed as little as 5.443 grams when struck and been of legal weight.

   From what sources are you learning about coins in general and mint errors (an advanced topic) in particular?

Stay away from YouTube and assume that 90% of "error"coins on eBay, and 100% of "error" coins on Etsy are actually damaged coins. Reliable sources include Coin World,  Numismatic news, anything put out by the ANA, this forum, and forums on Coin Community, Coin talk and PCGS. There are other good sites, but these should keep you busy.

   Unfortunately, the internet has become flooded with misinformation about coins, especially mint errors. Please read the following recent article by a prominent coin dealer: Jeff Garrett: Fake News and Misinformation in Numismatics | NGC (ngccoin.com).

   The following forum topics identify reliable print and online resources from which you can learn about coins:

Yes, NOT most websites.

Hello and welcome to the forum!

I always recommend to new people coming into the hobby a couple of books to begin with. The first called A Guide Book of United States Coins (commonly referred to as the Red Book), 78th Edition, 2025. This book has a wealth of information for newcomers and is widely used by many in the numismatic community. The second book being The Official ANA Grading Standards for United States Coins, 7th Edition. The second book will help with pictorials of the coins in different grades.

Avoid most internet sites or videos, except for NGC, PCGS, ANA, ANACS, The US Mint, and The US Treasury. Anything beyond that likely has more misinformation than good information.
