Hello, few times I came across the values of coins in a catalog that are higher for coins in lower grade. I am just curious, since generally the coins in better shape (higher grade) should have higher selling values and vice versa. The example is here: https://www.ngccoin.com/price-guide/world/italy-500-lire-km-98-1958-2001-cuid-1201546-duid-1472888 500 italian Lire, 1958R, which is listed 20.50 in XF40 grade and 16 in MS60 grade. What is the explanation?
This is a very annoying glitch in the NGC/Krause database, which affects at least dozens of types (and who knows, maybe hundreds). I encounter it all the time. I guess if you carry that MS60 coin in your pocket long enough to wear it down to XF40, they're paying you for the work by making the lower grade more valuable. Seriously, though, it's an error, a very common one with them, and I wish they would fix it (and all the others). But the catalog is huge and their staff, as I understand it, is tiny.
Makes you wish they'd find a way to take on some volunteer proofreaders, or maybe put a "report errors" link on every type's page.
From time to time, the same thing has happened in Numismatic News' monthly pricing section, but when I find one, a quick email to Dave Harper usually gets it fixed by the next month.
If ever there were a coin where such a fact made sense, it MAY BE the 1950-D nickel. Far easier to find in high grades than in low.
As Kurt's fine example, the 1950-D Nickel was saved to the hilt making circulation grades more difficult to find. Supply and demand bump the price up for lower grade coins.
Sure, 1950-D nickels are more common in Mint State than in circulated grades. That doesn't make the MS coin worth less than the circulated one! Sure, it might narrow the price spread, but a circulated coin will never be worth more than a Mint State example in the real world, or everyone would "circulate" their MS coins to reduce them in grade, which is an absurdity. This is, as mentioned, merely a catalog glitch with which this particular database happens to be plagued.
I always assumed this was based on auction results. I can see a lower grade selling higher than a higher grade that way for multiple reasons - long time between sales, or 2 people getting into a bidding war over a lower grade vs a higher grade that may have been a good deal, etc.
NO. This is a glitch, pure and simple. There are far too many cases of it in the database. Including on very cheap, common types that don't sell at major auction. Trust me. Scenarios like you mentioned do happen on an individual case-by-case basis, but not, to my knowledge, enough to affect catalog pricing in absurd ways like this. The coin in the OP is a relatively common type. The column error is also, sadly, very common.
I believe these happen because Mint State coins and circulated coins are updated at different times, and maybe by different people.
