The 1858-S and 1853-O likely had PVC as both show corrosion. I don't see PVC on the Texas. What do you see on the Texas that makes you think that?
The discoloration is a similar Grey to PVC, there are some small green spots also. I don't think they are corroded, I think they could use some time in pure acetone.
A nice upgrade from my AG3. I couldn't resist this coin and am delighted to win it. Now I have to sell the other two to afford this one. PCGS VF25
I have very little Seated stuff in my collection right now. Here are some Ancient and World coins that sorta fit the "Seated" theme. Alexander the Great, lifetime drachm Tiberius, "Tribute Penny" denarius Caligula, VESTA as Nero aureus Vitellius denarius Great Britain "Cartwheel" twopence Peru, 100 soles, Seated Liberty type (1.3 oz. gold!)
I agree that the CACG 1853-O and the 1858-S show clear signs of corrosion. The 1858-S looks burnt and I wouldn't be surprised if there were some cupric salts (green spots) on the surface. I don't care for either coin. They were sent in as test coins to see what floats and sinks in CAC's world. The color on the Texas is more brownish and lighter than shown. I haven't seen any green spots or other problems on the Texas. It has also received an acetone dip and will receive another as I'm about to submit it to PCGS for grading. It looks like a normal toned coin to me, but I have a lot to learn about grading issues. For example, I would reject the CACG 1853-O and accept the Texas if I were grading these coins because of the bands of etching and pitting on the obverse of the 53-O. The 53-O looks like the surfaces were strafed by an A10 Warthog. Oddly enough, I have probably a dozen photo examples of corrosion and cupric salts on CAC-stickered coins in my "CAC Hall of Shame" file. CACG graded the 1859-S with VF30 details as VG10, when IMO, it should also have been rejected for "black schmutz" and correlated corroded surfaces. Thanks for your comments! I'd love to sit down and show my coins to other collectors for their comments and pick their brains on grading. I feel that is something I've missed by collecting off eBay and not getting input from other collectors and graders on my coins.
Very nice early Seated dollar -1840-P.! Not too common - despite years of trying I still don't have one of any date. They're quite expensive: maybe someday? Would love to get an early date like this. Also would like a Trade dollar. Someday maybe...
I decided to look through the first 180 1877 (P and S) halves on eBay. After 180 coins searched, I found two '77-S WB-38s (R5), a '77-S WB-25 (R5; labeled as such), and this '77-S WB-6 "Weird F" (R7). The seller's photos make it appear to be cleaned, but I don't see any hairlines and figure the cleaned look is a lighting effect. Instead, the obverse has a mottled pattern with some amber orange toning on and around the devices, and gray to black, slate blue toning elsewhere in the fields. The reverse is similar but with more color and mottled toning. The only significant problem I see is the scratch across the shield, legs, and in the right field that might prevent it from straight-grading. Seller's photos - show some color and shows the weird F more clearly. My scans - show the overall toning pattern.
