Some really nice coins here. A nice toning/patina is one of the things that makes collecting ancients so enjoyable and challenging. Especially with patina, it seems to take a thousand years or more to get some interesting colors going. I have a rather strange blue (partial) patina (or deposit?) on a follis of Phocas I got a few years back. It seems to be inert. The photo is a pretty accurate depiction of the color.
I also like green patina: TRAJAN, SESTERTIUS, RIC Vol. II, Rome, No. 534, 98-117AD, Obverse depiction: Trajan, head facing right, wearing aegis Inscription: IMP CAES NERVAE TRIANO AVG GER DAC PM TRP COS V PP Reverse depiction: Trajan galloping on horseback spearing a fallen Dacian soldier Inscription: SPQR OPTIMO PRINCIPI - in exergue S C
......... also dark brown/black with lighter brown highlites: CLAUDIUS, AS, RIC Vol. I, Rome, No. 113, 41-45AD, Obverse depiction: Claudius, bare headed, facing left, undraped bust Inscription: TI CLAVDIVS CAESAR AVG PM TRP IMP PP Reverse depiction: Personification of Liberty standing right: pileus (freedman's cap) in right hand Inscription: LIBERTAS AVGVSTA - S C (left and right)
..... and I do have a soft spot for “milk chocolate” brown: NERO, SESTERTIUS, RIC Vol. I, Rome, No. 356, 66-67AD, Obverse depiction: Nero, laureate head facing right Inscription: IMP NERO CLAVD CAESAR AVG GERM PM TRP XIII PP Reverse depiction: Personification of Roma seated left on cuirass resting elbow on shield and holding spear, helmet behind Inscription: ROMA (in exergue) S C (left and right)
..... and I do like folles that retain their original silver surface wash - as long as it is not too blotchy: CONSTANTIUS, FOLLIS, RIC Volume VI, Lugdunum, 17a (Invasion coinage) Obverse depiction: laureate, bare neck, bust facing right Inscription clockwise from bottom: FL VAL CONSTANTIVS NOB C Reverse depiction: Genius of Rome standing, facing left Inscription: GENIO POPV -- LI ROMANI
That's a really good point, OJ. Gordians do tend to come over-cleaned/too shiny. An otherwise unexceptional example can look much better with some toning. Most of mine are bright white - but I prefer 'em toned: Gordian III Antoninianus (243-244 A.D.) Antioch Mint IMP GORDIANVS PIVS FEL AVG, radiate, cuirassed and draped bust right. / FORTVNA REDVX, Fortuna seated left holding rudder and cornucopia, no wheel below throne (Rome). RIC 210; RSC 98a; RCV 8613 (3.11 grams / 22 mm)
I'm definitely most partial to a sandy desert patina. But here are 2 other types of patina of which I wish I had more. Darkly-toned silvering: Hoard:
So many stunners! I too, am partial to a good green patina, but alas don't have any great examples. The black patina on this coin from Mysia, Pergamon (c. 200-30 BC. 17mm., 3.77g. Laureate head of Asklepios right / AΣKΛHΠIOY ΣΩTHPOΣ. Serpent-entwined staff) is a favorite. https://www.forumancientcoins.com/gallery/displayimage.php?album=7009&pos=5
The unusually colourful patina on this drachm is a party on a coin. A-Pi. EGYPT, Alexandria. AE Drachm. RY 8. Tyche. Ex stevex6 Collection
Heavy red patina on this double sestertius of Postumus, not exactly pleasing but definitely interesting.
