My other snipes are too old for eBay to bring up . . . But I think the above examples are typical of my more extreme examples for me.
These are a couple of my better pick up with snipe bids or high proxy bids....
last year 1933 Zeenut DiMaggio snipe set at about $3000 won for $1200.
Only known 1925 Holland Ice Cream #16 card (Peckinpaugh) proxy bid of $2500 won for less than $200, then sold it for over $3K a year later.
Last week I set snipe bids at $300 ea for 7 different auctions and won all of them for less than $60 ea.. I cant tell you more because the same seller listed a few more of these extremely rare and somewhat unknown cards that will end this week. I plan on getting them all again. In the past I have seen them sell for $200-$300 when they do hit the market once every 2 years or so.
A similar story, I picked up over 10 individual auctions for 1938 Sawyer Biscuit cards a few years ago for roughly $25 ea........ at the time they booked for $200 ea. now they book for $600+ ea. Too bad I flipped them for only $150 ea. as a group a couple years ago.. should have saved them they now sometimes bring 2X times book if you ever find them.
