I put in a couple of extra digits! This is with the microscope touching the holder, so this is the best I can do.
Try this as shooting a proof can be hard to do because of the back scatter off the coin. Place the scope on the date and focus . Then turn off the LCD light and use a small light source from the side to illuminate the coin. I use a small pen light or something I just purchased a set of clamp on book lights. I'm just wondering what is under those crazy 8's
Focus is set to the surface - you can see the flow marks. Two different lighting angles. Who's living in my 8's?
Thanks for doing the images, as for what's living there , is the reasons I asked for better images. I'm not sure but Did see what ever it is as well as admired the coin . I'm not sure if it's die chips or a reworked die ,file lines, or another digits that someone tried to hid or remove . Maybe someone else can shed some light .
The 8's are definitely re punched.....Looking in the red book for mintage numbers....1887 were only (2960) proofs minted. And 5001 MS were minted. Next they list a 1887/6 no mintage numbers . 1888 (4582) proofs minted. I wonder if we could find another 88 proof on line to compare the dates? Next I'm wondering if they didn't use another die , reworked it since the mintage is so low? That makes sense as if you compare all of the mintage's why would they commission a new die to strike so few coins?
I found this on the NGC Coin Explorer site: "The popularity of coin collecting in the USA reached a peak around this time that it would not experience again until the late 1930s. Sales of the 1888 proof three-cent piece were quite high, though at least some of these were sold early in the following to dealers who purchased the remainders at face value. Hoards of this and other dates from the period existed for years, and it was the need to market such hoards that prompted the development of the first coin albums in the late 1920s. 1888 proof three-cent pieces are fairly common in all grades through the gem level, and even cameo examples exist in sufficient numbers to be collectable. A minor repunched variety is known for this date but commands no premium." Then I went down to the condition census part of the page, and went to the first PR66CAM listed and followed the link to Heritage. https://coins.ha.com/itm/proof-thre...-ngc-census-52-12-/a/1233-7156.s?type=NGC1233 Not only do I see these marks, but if that coin was graded Cameo, then my identical coin should have been, too.
Maybe you should start a new thread so we don't hijack this topic. I have an image to share. compare what is going on with your specimen to the images above . I'm convinced that the proof dies were reused,and re tooled
The reverse of yours may have kept it from receiving the Cameo designation. From your video it looks like there may be some frost break in a few areas. Of course that could be from light artifacts.
Few new coins for the dansco, also got a 1906-S Barber dime but they went right into the book before pictures.
