Posted By: <b>jay behrens</b><p>You probably want the median price rather than average. That $2.8m sale would really skew the average. Doing like they do with home prices and taking the middle price of all sales would be more accurate.<br /><br />Jay<br><br>The richest person is not the one who has the most, but the one who needs the least.

Posted By: <b>ItsOnlyGil</b><p>You are probably right Jay, I never did pay attention that day when they explained the difference between average and mean. Nor was I much good after the five times table (until 10 + 11 !!! ..... but then they hit us with the twelve <img src="/images/sad.gif" height=14 width=14> ) Hard to believe I'm involved with (non-choo choo train) engineering.

Posted By: <b>peter chao</b><p>Impossible to calculate. In general, we only know about the price of cards that are exchanged on the internet. But how about the price of cards that are being exchanged at card shows and stores. Then there are cards that are exchanged between friends.<br /><br />Any estimate as to the percentage of cards that are sold over the internet?<br /><br />Peter C.

Posted By: <b>davidcycleback</b><p>You can average items, but that does not mean an average item exists. <br /><br />If one item sells for $1 and another for $999, the average sales price is $500. I'm not aware that the $500 represents anything meaningful, and it certainly doesn't represent any sale.

Posted By: <b>Bobby Binder</b><p>I could dig in and tell you the average price of graded cards only...but it would take to much time. We have some great stats on VCP that is interesting to see in our AMR section.Few interesting numbers so far this year in auctions for graded cards total $59,535.306, this week $1.004.784, this month $8,154,847 and there is a lot more to check out.

Posted By: <b>Gilbert Maines</b><p>Yes Bobby, the thread had no real point. It was solely intended as a meaningless diversion.<br /><br />But you are right, your site would be a fun playground to determine all sorts of information. And conduct a variety of analysis.

Posted By: <b>peter chao</b><p>Bobby,<br /><br />I have a serious question for you what do you think is the percentage of vintage cards that is sold over the internet?<br /><br />Just an estimate, I'll take a wild guess and say 25%. I believe that most sales are still done at card shows and shops. Meeting the seller and personally inspecting the card is still important to most buyers.<br /><br />Peter C.<br />

Posted By: <b>Russ Bright</b><p>I disagree - I think closer to 60% of all vintage card sales happen on the internet - maybe more - most of the card shops in my area (and surrounding 100 miles) haven't even SEEN some of these cards- and when i mention what i have they're ALL amazed that i could even FIND cards like these - or if you find the shop owner that has 1 or 2 T206's they're 100 dollars for a PSA2 common - as far as average price? I would say 40 dollars - you can get a lot of common cards for most sets for 20 or less - but with the high prices of some of the higher profile cards bumped it up a little bit -

Posted By: <b>peter chao</b><p>Russ,<br /><br />I would think that your figure of 60% might apply to the shiny new stuff because people think that new cards have fewer problems on them.<br /><br />But for the vintage stuff you are talking about higher dollar amounts and more problematic cards, the 25% figure is probably pretty close to the actual percentage.<br /><br />Peter C.
