Getting Prices Of Genuine(Not-Gradable)-Various Conditions

Imo, there is no set formula. It all depends on how much damage there is. Have seen the same labels on holders, but the coins had quite different degrees of damage. Buyers know this and seem to evaluate each coin on it's own. Not sure if that helps. Sometimes you can get a deal, but if the pics are good, everyone sees the same coin you do, and bids accordingly. Have cherrypicked a couple of 'details' coins, but not many.

I understand that you would like to be able to establish a firm set percentage value on coins that were either details graded, or not gradable in comparison to an established price.

The number of people who will simply not buy a details coin is great. Usually it takes some time for a collector to establish a pattern of buying certified coins. Or, in a few cases, someone might buy encapsulated to break out (not a wise choice). In either event, you will see that most collectors who have switched to buying encapsulated either exclusively or a good percentage of the time are those who arrived at that decision because they are more comfortable with slabbed pieces.

This is especially true of buyers who purchase multiple hundred or thousands of dollar pieces. You will also find that once a collector has begun to buy encapsulated, it may eventually be considered their only option.

Problem details coins are almost exclusively attractive for one of three reasons: (a) It is a key date that would cost too much for a collector and having it in any slab at least assures authenticity the great percent of the time, or (b) There is such a huge price difference between a righteous coin (such as early bust issues) and a nice looking incorrectly cleaned piece that it's worth considering, or (c) the buyer thinks it's cheap and will bid or buy cheap.

Your attempt to give a percentage for the potential price of a righteous slab and one from the same company that has a problem is absolutely impossible.

As it should in all cases, it depends on the coin. Even in a righteous slab there are huge differences in price because of eye appeal.

Find an MS-65 Walking Liberty 1942-s or 1944-s with actual strong strike and it may easily sell for 2 or 3 times the average - and the list could go on an on.

The same is true of the details grade. The problem itself will determine what someone is willing to pay.

A scratch across the face will have few buyers, a scratch in the hair in the same direction as the hair, might be a good buy. Spotty terrible half cleaned "measles carbon spots" all over the coin as opposed to a light brush that has retoned as opposed to a harsh scraping, all types of cleaning, will also make a huge difference in value.

As is true of every type of details grade.

There is simply no fun and easy formula. It depends on how many buyers are eliminated from the potential buying pool more than anything else.

I look at the coin and think if someone offered to give it to me or a problem free coin in various grades, what is the lowest grade I would take the problem free coin in? That is my value of the coin with the problem. Sometimes it is -1 grade, sometimes more.

I saw this Draped Bust half so harshly cleaned, it was shiny white and had nothing original about it. It had Unc details. I figured I'd prefer an original XF over it, but would probably take the coin over an original VF, so I valued it at around $800.

I saw a Bust Dollar that had had graffitti removed and was smoothed in the region of the repair. The coin was otherwise VF. It was being sold for VG money, so -2 grades. Minor cleaning or a rim ding would be, maybe -1 grade.
