I don't know if this is what you had in mind, but this probably the top of my skills with Excel.Beercanpete wrote: ↑Tue Jul 19, 2022 9:01 pm If I had lives enough, I've thought for a long time it would be interesting to learn some techniques from my son (who just graduated with a Master's in Data Science) where one could access all the data available from previous auctions and put it together in some coherent format. It could be done, but I don't know the tools well enough to do that. Can you imagine having 5-10 years of data for every can in USBC I and II and the Lilek books to pore over? Hours of fun and a valuable guide for all of us!
@dmorean Thank you Dan, for allowing everyone access to your Auction history on your website. Without that, I could not have done this.
Details worth knowing...
- Total of 39 Auctions between February of 2017 and July of 2022.
- Total of 14,636 items auctioned off.
- I assigned each auction an ID using "DM" and a numerical value based on the order that the auctions took place.
- I broke the items down into the following categories:
Cone Tops, Crowntainers, Instructionals, Flat Tops, Zip Tops, Pull Tabs, Gallons, Test Cans, Drinkware, Signs, Lithos, Knobs, Trays, Tip Trays and finally Miscellaneous.
You can only compare items with the same CAN ID. Luckily, a lot of the named items included a CAN ID but that created a different problem. Computers are stupid. They recognize "0" (zero) as a number. I had to go through the entire list and add a zero to and single digit number (170-9 had to actually be 170-09 in order to sort properly).
The cans that had no CAN ID, well, I had to go to each location in the archive and see if it had a CAN ID number. THose that had no reference number or were designated as unlisted are shown as "N/L".
Mr. Morean's archive was never intended as a true database, just an informational record. Pick a named brand group and you'll see naming variations, misspellings, skipped punctuation marks and such. This is the reason a CAN ID is critical data. Click to enlarge.
Once the CAN ID's were finished, I sorted each brand by those CAN ID numbers. Then I also sorted each group by their respective dates. So, find a can you're looking for, select all with the same number and you'll see the selling dates for each.
I thought of several possible layouts and settled on this one, possibly being the easiest to use and understand.
It's in PDF format even though I did the work in Excel. I doubt anyone would want to print it anyway.
Side Note: I wanted to include the Good Guys Auctions but their archive has a programming glitch which I have mentioned to them. Maybe a future project?
Also forgot to mention that my detailed searching found 41 Crowntainers labeled as Cone Tops (list at bottom of final page.) It looks like every Crowntainer in the proper category was named "Crowntainer Cone Top". These 41 omitted the word "Crowntainer" from the Item Name so they ended up in the Cone Top category.
