Two Visually-Stunning Colorfully-Toned Lincolns ... (Outstanding Photography by Robec)

I just got these photos back from Robec this week (who did an outstanding job!). Both of these coins were raw pickups at bargain prices (for this kind of color), $14 for the top coin and $10 for the bottom.
This first coin (1959 Mint State Lincoln Cent) came out of an original paper roll of 1959 Lincolns, where many of the coins in the roll exhibited a similar toning pattern. I have bought a number of them from the seller, but this one example appears to be the best that I have seen come out of that roll. Colorfully-toned 1959 Mint State Lincolns are actually kind of rare (from my experience), other than this extraordinary roll, since 1959 was the first year (in about 12 years, I think, 1947-1958) that the U.S.Mint did not use those sulfur-laden cardboard holders to distribute Mint Sets, which dramatically increased the population of colorfully toned Lincolns in those years. I am guessing PCGS will grade this coin MS66RB, and will find out in a few weeks.

This next coin (1964 Proof Lincoln Cent) has a "Winter Chill, Summer Fire" look -- cool silver ice on one side and molten burning fire on the other. This is an important coin in my research of toning as it's the first silver-toned Lincoln that I have ever seen where the silver toning blended into other (non-standard) colors (as clearly seen on the reverse). Until now, I have only seen silver toning (on copper coins) with a hard (distinct) boundary typically displaying a silver to copper color transition or solid silver color on one or both sides. By the way, I am not exactly sure what causes copper coins to develop silver colored toning, but I have seen a number of examples of this (all, I think, were proof Lincolns). (I have wondered if the silver color has something to do with the zinc content?) In any case, this coin has finally made me doubt my previously held informal theory that silver colored toning on copper was not really "toning" (in the classic sense of the word), but really a "discoloration" that has different visual properties (more solid looking) than more classic copper toning (which tends to be more transparent and blends more). The reverse of this coin is now making me think that silver colored toning is actually true "toning", since it's so clearly blending in with other classic toning colors. I am guessing PCGS will grade this coin PR67RB.

In any case, Robec did a masterful job with the photography!
