Question - Historic Auction Prices (Bounty)

[bitvote]

Question for the community - has anyone here tracked historical auction prices for casascius coins? I'm curious how the premium changes over time.

If this has been done, would someone please provide a link to the resource?

If this hasn't been done (or if it needs updating), I'd be willing to offer a bounty (0.01 BTC) for someone to put this together. If there's any interest in contributing to the bounty, please +1 by adding what you'd be willing to contribute.

For clarity: I'll pay out the 0.01 BTC when the following conditions are met:

- An up to date spreadsheet has been created that incorporates sale information for all publicly available casascius sales listed on bitcointalk.org
- The spreadsheet should include the following information
(1) Detailed information on the coin (year/amount/version/additional notes on special features),
(2) Price paid
(3) Premium
(4) Date listed
(5) Date sold
(6) Link to the auciton post
(7) Seller name
( Buyer name
(9) a column for any special notes

I reserve the right to add a few additional elements to the requirement spec for the next ~72hrs (through Jan 28, 2018 - 10am pacific time)

If you've got ideas for other things to track or want to contribute to the bounty - please jump in!

thx

Not that people won't be willing to help, but if you were to put that 0.01 BTC with an escrow, it would go a long way in increasing participation.

I'm cool to do escrow - minerjones, would you be willing?

I do realize that the data is in the post history, but I would love to have someone else do the work of digging through it and pulling it all together into a resource that is easy to read and that would be publicly accessible to everyone in the forum.

and that takes real work. I'm happy to pay a bit to incentivize that work, but I don't really want to do the heavy lifting myself.

thx all.

  That would be very nice of you!  To publicly display this for us as a reference guide would be awesome and appreciated too! Thankyou!
