No it's not rare. More than 80 million were made.
Not much more than circulated state quarters. They're not old or rare enough to be especially valuable.
If you mean 1979 quarters without mintmarks? 515,708,000 were released into circulation from the Philadelphia mint. 1980 was the first year a "P" mintmark was used on quarters.
There were only 400,000 of them made which makes it extremely rare.
They aren't rare, they are, however 90% silver and worth a bit over $5 each at the time of writing in silver content alone. Many, many, many, pre-1965 quarters were made but simply the fact they were made out of silver is what makes them valuable. Now, there are, of course, some rare years of silver quarters, but there are also very common dates (like 1964).
Not rare at all and likely never will be so many were made and saved mint stae coins are very common
