For my Lincoln Wheat DATE set, the last hole I had to fill was 1957. I wanted a coin graded MS67RD with a CAC sticker, preferably the lower cost 1957-D. This way my set would be 100% CAC stickered in the grades I want. After searching vigorously for over a year, NOTHING showed up in auction that fit the bill. As such, human nature took hold when I saw (and bought) a lovely 1957-D Lincoln graded “only” MS66RD, and no CAC sticker. A VERY inexpensive coin!
So while I waited for an upgrade to the MS67RD grade I wanted, along with a CAC sticker, I figured what the heck. I was sending a few coins to CAC, so I threw in this MS66RD Lincoln with an extra $16. Sure enough, it got stickered!
I got my MS67RD with a CAC sticker upgrade a short time ago, so the lovely but cheap MS66RD 1957-D Lincoln, now with a CAC, is up for auction at Great Collections. I had them start the bidding at only $1, and it is now at $14, lol. My guess is the final price on March 5th will only be around $35 or so. I believe this might potentially end up at a record low price
PAID for any problem-free attractive Mint State coin graded by PCGS with a CAC sticker.
Interesting tidbit - I just checked the GC Coin Auction Archive and the PCGS Auction Prices Realized - neither shows ANY 1957-D Lincoln Cent graded MS66RD by PCGS with a CAC sticker as having been auctioned. As such, whatever it sells for will set TWO records for that date and grade - the lowest price ever paid, and the highest price ever paid (according to their records), lol.

I edited my post to capitalize the word “PAID” which was in my post originally!

I'd be happy to take some of your wonderful PCGS CAC coins off your hands for the absolutely princely sum of one cent.
It'd be one for the record books!
Regular price was $10 each for successful stickering and no charge for failures for Collectors members.
$13.00
Thanks.

In collecting obw cent rolls, the late 1950’s wheat cents are easier to find.
Interesting how touting the lowest price paid or sold for a nice PCGS/CAC classic date mint stare coin is a source of pride for the former/new owner! LOL
The PCGS slabbing fee is much higher than the CAC stickering fee to boot.
