Tracking The eBay / 24hgold.com PM Price And Premium Widget

I have undertaken a new project, much smaller in scale than my earlier one to categorize Zero Hedge articles.

I have been interested in that widget ever since I first found it (at 24hgold.com, at the bottom of the home page).  It is a very imperfect measure of physical demand vs. paper gold price at the retail level.  Yes, I know it tracks Gold and Silver Eagles only, but that is what the widget itself tracks.

I have just started this, so the below results are NOT particularly meaning (except for the majestic 115% premium of ASEs over spot, I have seen it at over 80% but never over 100%) because of the very short time frame.
Note that typically AGEs run some 5.5% - 8.5% over spot.  The LARGER numbers here I have often seen when PM prices PLUNGE like they have lately.

As time goes by, this information might become more useful, I am hoping that it will give us clues as to when the physical markets for gold and silver get tight...

I very much would welcome ideas and suggestions!

EDIT:

I lost price data (spot gold and spot silver) when I published this (the farthest right two columns did not come through).  I think I will produce this in future posts with a GoogleDoc link, as I know how to do that now.

RE-EDIT:

Published in the cloud, this link includes price data for Au and Ag:

Notes:
1)  All premiums are truncated percentages, high precision not necessary IMO
2)  I have noticed that premiums widen when PM prices go down.
3)  Gold and silver prices are from 24hgold.com.  ["formatted out"]
4)  AGE = American Gold Eagle 1 oz, ASE = American Silver Eagle 1 oz.
