1884 O Morgan Dollar Blue Toners From KS Coffee Can - Opionions Please

Waited to long to edit, wanted to get a better shot in on the blue 1881 S showing even toning.

Frog, can you edit/pull the 1881 S ? I agree it confuses the layout. Thanks.

I'm assuming that:
photos 3 and 4 are the obverse and reverse of the 1881-S
photos 5 and 6 are the obverse and reverse of the first 1884-O
photos 7 and 8 are the obverse and reverse of the second 1884-O

Photos 3 and 4, 1881-S. This is the nicest of the three coins. Like the others, it appears to have had an old cleaning, with some retoning. The obverse has few contact marks of consequence: a few dings on the neck and a fairly evident gouge near "UM" of UNUM. The obverse marks are consistent with MS-64. The reverse has some minor divots near the upper left wreath and some small contact marks in the field east of the eagle's left wing (our visual right). These are consistent with MS-65. From a technical grading perspective, I see the blended grade as MS-64. Eye appeal is problematic. There seems to have been an older cleaning, followed by retoning. This is evident on the rims, on the reverse (note the residue on the eagle's right wing near the first "S" of STATES). The retoning appears unnatural , especially on the rims and reverse. I see a full point eye appeal deduction, with a resulting grade of MS-63. IMHO, the old cleaning on this coin is market acceptable and the toning is not so far off as to cause the coin to be detailed with a 91 code.

Photos 5 and 6, the first 1884-O. This coin shows evidence of minor circulation. On the obverse, this is evident on the cotton blossoms, hair over the ear and above the eye, and bear claws and lower curls. on the reverse, it is evident on the tips of the wings, left talon, tips of the tail feather, bow, and parts of the lower left and right wreaths. I see the coin as a classic slider, with evidence of an old cleaning that was followed by mishandling (note the heavy fingerprinting, especially on the reverse). Classic slider, AU-58, maybe AU details.

Photos 7 and 8, the second 1884-O. The obverse and reverse do not show signs of circulation. the obverse has several contact marks, many of them fairly visible and deep enough to affect the grade. There is a heavy scratch west of the neck, multiple contact marks on the neck and cheek, contact marks west of the nose, and contact marks between the cap and the sixth right star. IMHO, these are consistent with MS-62. The reverse is better. While there are numerous small contact marks on the rim and peripheral lettering, there do not appear to be any deep contact marks on the devices or fields. The reverse is consistent with MS-64. The blended technical grade would be MS-63. Eye appeal is lacking. The coin appears to have had an old cleaning, most evident with the heavy fingerprinting on the reverse. The obverse has a circular stain across the cheek, likely from long-term contact with another coin. I see a full point deduction for eye appeal, with a resulting adjusted grade of MS-62. There is a risk of the coin being detailed because of the older cleaning and environmental damage.

Cannot reconcile the pics of the 1884-O, so I'll not offer any opinions.

well, not the best in eye appeal. they have definitely been stored for a while and not properly for sure but they would most likely grade straight. most look high AU that you are showing here.

Blue toning of silver commonly relates to reaction with potassium ferricyanide. One source is processing photographs. Blue toning like that shown in the last group photo rarely is natural. It's possible, but not common.

EDIT: Just a thought. Was this coffee can ever used to store small quantities of ice melting compounds? They sometimes can contain potassium ferricyanide.

Thanks for the opinions, asked the seller about the coffee can provenance and he smiled and commented "how the heck would I remember that". Something though (compound) caused this blue hue and I tend to figure most radical first (dipping) followed by trace compounds of chemicals in can. Not worth slabbing but their in airtights intended for x-ms stocking's. Studied some slabbed PCGS 1881 and 84 gems blast white for under $150.00 that were stunning to behold, ha the 3 pictured looked malaria stricken next to the gems. When I do get to this series am definitely proceeding with patience and caution, fascinating series IMO pennies and nickels are childsplay in comparison, I am nearly ignorant in the basics of Morgans have started studying and describe it as daunting but very stimulating.
Thanks for input all.
