I know this topic has come up a few times over the years.
I was absolutely floored to see the results of the Huggins & Scott tabbed Zeenut examples.
Having been an active bidder, I was definitely surprised to see that both of these cards were among the last items to close the auction:
1917 Stan Dougan with Coupon sold for $960 (w/vig)

1916 Ping Bodie with Coupon sold for $1920 (w/vig)
http://www.hugginsandscott.com/cgi-b...l?itemid=15969
Now, both were high grade, and certainly Zeenuts with tabs from the 1913-1922 timeframe are especially scarce.
However, as a frame of reference, this lot recently sold in REA for $1,320:

which contained tabbed Zeenuts from 1913 and 1914, as well as four other Zeenuts, including a high grade 1911.
