They aren't. A lot of 1972 quarters were minted, none of them contain silver. They are worth only $.25.
No 1972 US quarters have silver in them, the last year for silver quarters was 1964. so spend it
Quarters from 1964 and earlier are often more valuable than those from later years due to their composition; they are made of 90% silver. As a result, their melt value exceeds the face value of 25 cents, especially when silver prices are high. Additionally, quarters from specific years or with rare mint marks can also be more valuable to collectors. Collectors often seek out these older or rarer quarters, making them more sought after and valuable.
Not much more than circulated state quarters. They're not old or rare enough to be especially valuable.
All circulation-strike quarters dated 1965 and later are made of copper-nickel, not silver. There are no major varieties among 1972 quarters, so anything that you find in change will only be worth 25¢.
The 1972 American Revolution Bicentennial coin is made from brass. There are versions of the coin that are somewhat valuable.

Quarters have been issued since the 1790s so there are many years and mint marks that are valuable. You can get an overview from a site such as http://www.coinclub.com/prices/ At least within the last hundred or so years, two of the most valuable quarters are a 1901-S Barber quarter and a 1916 Standing Liberty quarter.
the value of the painted quarter is worth the same as a unpainted quarter

Do you mean 1,997 quarters, or quarters from 1997, LOL? In any case they're worth 25¢ each. Out of curiosity, because these are readily available in pocket change, what made you suspect they are valuable?

All the 1999 state quarters are worth more than the other years. That is b/c it was only minted half the year vs. a full year. Typically, you'll find half the quanity as the other state released quarters.

To determine which is more valuable, we need to consider the weight and height of an average person. A pile of pennies equaling your weight would be worth around $1.00 for every 2.5 pounds, while a stack of quarters equaling your height would be worth approximately $20 for every inch. Since the average person weighs around 170 pounds and is about 5 feet 7 inches tall, the stack of quarters would likely be worth significantly more than the pile of pennies. Therefore, the stack of quarters is more valuable.
Quarters dated 1964 and prior are 90% silver and worth about $5.50 at the time of writing just in pure silver content. 1916 Standing Liberty quarters are key dates and worth quite a bit. Coins in their original mint packaging are worth a premium, especially if they are proofs.
None of the bicentennial quarters made for general circulation have any silver or are worth more than face value. Only Proof and collectors coins sold from the US Mint are worth more.
