You probably want to make the distinction between "Mint in Shrink" and "Mint" out of shrink - there is a big difference between the two.

Also, just spot checking a few - the prices seem fairly similar to the "estimated values" posted on the Acaeum.

I think you can run into a lot of problems using eBay solds as definite values.

Seller states the item is complete, or unwritten in, etc. and it's not. If the buyer doesn't return the item for a refund or a partial refund, is that really the value of the item in it's particular condition?
Speaking of partial refunds, they don't show up in the sold price. I think they reflect just a small minority of the amount of items sold but I've gotten a few over the years.

What if the item is damaged in the mail? You may have paid $20 for a B-whatever in VF condition, but if it didn't get to you in that condition and you didn't get a partial refund. You didn't pay $20 for a VF book, you paid $20 for a book in whatever condition it came to you as.

Something too that I think gets missed a lot. The value of how a Seller sells. Some are better at it than others. Some are just bolder. I don't think averaging really helps a lot if you are looking for systems you can incorporate to help you in your buying. If you spend your time looking for the tricks to get the most out of your money, you'll ultimately benefit more. If your time is extremely valuable, you'll want to find the "best" sellers and wait for them to sell the item you want.

I agree with all of the above, as it pertains to "actual" or "definite" values, but I believe the information that Mick is providing us with is "Advertised" value. In other words, if a module were represented as Near Mint and there was no visual evidence to dispel that condition, then the bidders would bid accordingly. If the module received had highlighting, writing, underlining, missing pages, and coloring done to it that would not matter, as all we can go on is the condition of the module as it was 'advertised' or represented.

It would be great to really know all the facts, but I think this information is a good barometer of how prices are trending on average. Obviously there are a lot of variables at play. Even Mick admits he is trying to be consistent with condition evaluations, but I don't think any of us could be 100% accurate or consistent, so it is an overview which will have some anomalies based upon the number of data points and variations as mentioned before.

Personally, I would really appreciate it, if Mick is willing and has the time, to post the results of his app on a monthly or quarterly basis. It would be good information for both old collectors and new ones

Thank you both - Paul
