Mitchell,
At first, I thought this eBayer must have made a typo in his price listing for the 1878-CC GSA card, becasue I've never heard of a GSA card for this date selling for more than $35.
I looked at some of this seller's past eBay auctions and saw that he [I'm assuming the seller is a "he"] sold an 1885-CC GSA card for $90 (I usually see cards with this date offered for $25 or less). The seller's hype for this card was its number--85144446--which he described as "Very Cool," because it had four "4s" in it (I didn't know there was a subset of GSA card collectors who were interested in the digit combinations in the serial numbers).
This same seller must be on a roll with these GSA cards, because he also sold one dated 1880-CC for $150 two weeks ago. I usually see cards with this date offered for $20 or less.
We'll have to keep an eye on the sale of this 1878-CC GSA---a new wave of interest in these cards might be emerging.
