Washington Quarter Filled Mint Marks

I have noticed a LOT of P & D filled mint marks for the 70s and 80s, in circulated Washington Quarters. Since there appear to be so many, are they worth more than a correct mint mark?

sometimes you'll almost need to look at the other diagnostics just to tell a Philly from
a Denver. This is why they started making the mint marks larger starting in '81. (es-
pecially the "D" at first).
In 1981 all you could tell at a glance was if the MM was a D or a blob.
There are many exceptions but especially with the clad coins it's the well made ones
that defy the rules and are scarce. Well struck clads from good dies were quite diff-
icult to locate when they were new and now they're almost all heavily worn or lost
entirely. Finding well preserved specimens would be impossible for most dates were
it not for mint sets.
I can't think of any clads that have a premium for having minting defects though at
one time a grease filled die that resulted in 1989 quarters with no mint mark result-
ed in a large premium. There are lots of early date dimes missing letters or sets of
letters on the reverse that are fun to collect but these rarely trade at a premium. Die
varieties can be extremely rare and valuable in clads but not minting defects at this
time.

.....please enlighten us, sam. which 'other' diagnostics do you mean?

The '80 quarters have more differences between the mints than almost any other date.
From a glance you can tell them apart much of the time just by the flatness of fields of
the Denver. There is no single or combination of diagnostics that will differentiate them
all the time.
