Ebay historic price auction data

Do any of you feel there's value to historic auction prices for coins sold on ebay (I'm talking about NGC/PCGS) similar to buesheet but the actual selling prices/dates and including the auction numbers of coins sold and the sller/winning bdder (possibly even bid list).

Would any of you suscribe to a system that you could pull that info from? How much is that type of quick reference info worth- that is how much would you pay? Would you pay for a per use/session or a premium ofr continous access - i.e 1 month/1 year suscription?


I know that dealers/collectors and people just looking to get a fair price buying or selling probbaly scan the current auctions to get a 'feel'.

    To me, this would be more of a curiosity than having any value.

    In this rapidly changing coin market, I would think that any pricing data more than six months old would not be too useful.

  • I would like to be able to do a search of past auctions more than the 30 day limit they currently have. This would allow for an 'average' pricing calculation and a study of auction end dates/times evaluation.

    eBay is in a way it's own market. When you decide to sell something on eBay you can't expect to sell at any other historical value than what buyers on eBay are willing to pay. It's not like walking into a coin show where everyone is using greysheet or some other universally excepted value reference.

    There are so many variables to eBay bidding.

    i.e:
    Auction close date and time has a huge affect

    Category mistakes

    Picture quality

    ....etc....

    I think it would be valuable because many times I am looking for price data and the completed eBay auction data does not go back far enough. This isn't a problem for coins that appear on eBay often but many rare moderns don't appear all that often. Having a year or two worth of eBay data woud be valuable to me. A lot of the coins I am am interested in are modern rarities (flame suit on) and you can't get data on past sales. Heritage and TeleTrade are some help but eBay historic data would be great. I would like to have this data free of course image

    Very, very valuable. eBay is a legitimate market, and perhaps one of the most legitimate.

    Don't even THINK about it.

    Of COURSE it would be a good tool. With many uses other than just coins. But, being as the info would be derived FROM eBay, I would expect them to assert their rights to it if it got going.

    You MIGHT be able to ask them for a job developing it, but I sure wouldn't dream of using any info FROM them for your personal gain.

  • Ebay auction history for PCGS coins is one of the main things I use to get a feel for what coins "really" sell for. Also, Heritage price history and Teletrade history are useful.

    As for paying for the ability to search auctions history -- yea, I probably would. I'd want to pay on a per use basis. However, without pictures to go along with the prices, I wouldn't find it useful. I have seen many coins on ebay go for much more or less than the median price because of factors such as attractive toning, fingerprints, older generation holders, etc.

  • What value would a service have over something like:

    Ebay Completed Auctions for '37 Buffalo (need to login)

    or

    Teletrade Auctions for '37 Buffalo proof


    Also doesn't eBay charge an arm and a leg to use their auction data?

    Heritage has a wealth of past auction data. You have to join to access it but its free.

  • Good tip on the ebay data thing. I'll have to read into that..I signed up for teletrade, they actually have a promo for $100 on your first purchase. Might take em up on it.

    I'll start a new thread, but this may belong here. Is there much arbitrage - price disparity between teletraeand ebay. That is, buy on teletrade re-sellon ebay or vice versa?

    Depends on the series. For example, early date CAMEO and DCAM Kennedy halves sell for less, generally, on Teletrade than eBay. Yet, mid grade "rainbow" ('B' and 'C' box color) Morgans go for much, much more on Teletrade than eBay.
