Best way to approxiamate value

09sVDB

Most price guides list values for coins in MS60 and then jump to MS63. I have a key date Washington Quarter(32S) in NGC MS62. What would be the best way to value this coin as there is a pretty big jump between 60-63?

I'm interested in the answer, since I have one in NGC 61!

If you are buying it from a dealer it will be priced at just below the MS63 price. If you are selling it to a dealer you can expect the MS60 price and not a penny more. MS61 and 62 are not very marketable grades.

Great question! In the past, I have done mathematical interpolation on Corel(R) Quattro Pro(TM) (more powerful than Excel) to approximate an unknown value based on known values.

Use the Sheldon scale to find a mean.

I think There's a little more to it than that. Especially on an Ms-62 32-d. A lot depends on the quality of the coin in question

I have seen a varying degree of quality among 32-d washington quarters in grades 61 and 62. Some I would pay near 63 money for, others I wouldnt touch it at 10% back of ms-60.


I agree, auction results on comparable examples is the best source!

I favor a combination of the 291fifth and boz approaches

The blus sheet gives prices for both PCGS and NGC slabed coins in MS 61 and 62. This should give you a good feeling for the pricing

Since there are usually large jumps in price between, say, ms62 and ms63 (versus, say, ms60 and ms61), the relationship is not linear, so a mean will not work (best fit line). If you do some sort of interpolation, what you are really trying to do is a best fit curve. I'm an engineer at heart, so this is how I think. All of this is assuming you cannot get accurate data from past auctions, etc. Of course, don't waste your time on this for a $50 coin. I'm talking expensive coins here.

I did an Ebay search and came up with two. $1195.00 with no bids and the other with no info.

I checked the Bluesheet, Pat. It did not give me a good feeling! According to the Bluesheet, I've lost half my money in this coin I bought two years ago.

this is according to PCGS price guide (its an NGC coin blah blah blah)
Anyway, back to the interesting math question - and away from grading service and priceguide debate.
Grade

AU 60 63 64 65 66

275 450 1200 2600 7500 40000

just looking, 850 seems to fit for 62

550 for 61

Just as a rule of thumb, To calculate the value of the MS-62, I will take the value of the 63 and the value of the 60 and add them together and divide by two. So, if the MS-63 was $100 and the MS-60 was $50, the MS-62 would be $75. To calculate the value of the MS-61, I will take the now determined value of the 62 and the value of the 60 and add them together and divide by two. So, if the MS-62 was $75 and the MS-60 was $50, the MS-61 would be $62.50.

This rule of thumb is just to get you into the ball park.

Using my method from the previous post, my estimate on the MS-62 would have been $825. Also, my estimate on the MS-61 would have been $637.50.

Not too bad for a 10 second calculation.

If you only need the 61 price using this system, then add (60 price) + (5/32 * the 63 price).

Let us take a vote...

How many can multiply 5/32 times anything in their heads? I am pretty smart by most accounts and can't do it.

I think the Heritage auction archives are an excellent source. Some of the prices will be distorted, as in the case of PQ or under-graded coins realizing hefty premiums, but overall, it's a great resource.

Quarter Dollar = $.25 I'll give you .26 anyday!

Since it's just an approximation, take 15% of the 63 price (just like figuring a tip on a dinner check).

If the blue sheet does indeed have values for 61 and 62, then it is as simple as applying a ratio of the CDN 63 or 60 prices to the blue sheet 63 or 60 prices, and using that ratio applied to the blue sheet 61 or 62 prices. This of course assumes you have a quality coin worthy of CDN pricing.

In situations where a 66 or higher price does not appear on the CDN, you can do the same thing by getting a CDN to BS ratio in the 65 grade and applying it to the BS 66 grade. A general starting point for CDN quality is applying a 25-35% premium to the Blue Sheet. For some reason I find that 30-33% works best. The more ways you assess the potential value, the better chances of zeroing in on something that makes sense to you.
