PWCC Market Price Research, searchable ebay sales back to 2004

[Batpig]

Tried it, and the best thing about it that I found is I was able to search for box sales. I've got a couple early 2000's items that I've never been able to find comps for, but I was able to with this.

Gonna have to try it. Impressive and free. Never been a fan of paying for data I can get from the web for free. And I fully understand arguments on both sides.

"In total, this database houses over 200 million transactions and represents the single largest data set of prior sales ever presented to the public."

This is actually pretty sweet! Thanks for posting!

This person got a pretty decent deal on this card...

So I looked at the pricing data of two cards that I've had on my want-list for awhile. 1953 Topps cards of Mantle and Mays, in PSA 3.

Below is the price data going back to 2004. Note that I did take out a few outliers that just looked wrong and skewed the axis. Also, this includes both auction and BIN sales from the 'Bay. You can see that in the last 2 yeas, the difference in price has grown substantially. There are also quite a few more Mantle sales than Mays. I've always been intrigued by the comparison of these two center-fielders from NY, both on and off the field.
