Mintmarks were punched into individual dies by hand. If the punch shifted slightly between impacts of the hammer, you'll see doubling in the mintmark. While certainly interesting to study under magnification, this mintmark doubling was fairly common and doesn't add any value to the coin.
Worry is the interest you pay on a debt you may not owe.
1989 was the last year mint marks were punched into the dies by hand, which means you will not find any RPMs on dates after that.
@PerryHall Your statement about RPMs is not correct. If that is your opinion, you might as well say that doubled dies are fairly common and don't add any value to the coin...

Looks like machine doubling on both mint marks.

Doubled dies are created in a totally different manner than the mintmark impression. One is created during the hubbing process and the other is punched into the die by hand. It's not unusual for the mintmark punch to shift slightly while its being hit by a hammer. I guess we'll have to agree to disagree here. Without better pics I wouldn't rule out machine doubling though.

The Quarter was minted in 1994 so it can't be a RPM because the mint stopped adding mintmarks directly to working dies, as others have said.
The cent is difficult because the pics aren't good but the first closeup of the mm looks like it took a hit ( The raised part on the left looks thinner than a normal mm, which wouldn't occur if it was an RPM). Check www.varietyvista.com or www.doubleddie.com.

My point is that there are plenty of collectible RPM varieties that would add value to a coin, just as there are doubled die varieties that would add value to a coin.
I notice that you do not use the term RPM in either of your comments, and perhaps you are thinking of something other than a true RPM. Machine doubling commonly causes a slight doubling of the mint mark, but another common cause of slight mint mark doubling is when the mint mark is impressed into the die with a damaged punch (which did happen at times, especially in the 1970's). If a coin has PMD on the mint mark, that can also make it look doubled, and that is also common.
Generally speaking, the more popularly collected and valuable RPM varieties are those where the RPM has a relatively large spread, but that is not always the case. Sometimes rarity is a greater factor in the value of the variety.

Can't tell
Pics are way too pixelated.
best I can do
clear pics would be useful

Yes or No? All you needed to answer. I collect errors and varieties. Not trying to get rich. I know they are beat up!
Have you looked on Variety Vista for a match?

The cent looks like damage and the quarter machine doubling.....Cheers, RickO
