In August 2018 I started a thread https://www.cointalk.com/threads/byzantine-anonymous-folles.322682/ announcing my web site on Byzantine anonymous folles http://augustuscoins.com/ed/ByzAnon/ The many responses helped me improve it. Today I got in the mail a nice ("for type") Class F which I will add to the site. I got it on eBay. It cost under $15, including shipping, perhaps because it was not identified as the scarcer "Class F". 28 mm. 7.58 grams.

Nice one, Valentinian. Here's a countermark issue for Heraclius that I picked up - also on eBay. Rather to my surprise, it shipped from Israel, but since that is the area these supposedly circulated, I suppose that's a good thing. My host coin attribution is a bit of a guess. I think it is a bit unusual for these to be countermarked on the obverse - most I've seen have been on the M-side: Heraclius (c. 633-636 A.D.) cm on Tib. II Con. (578-582 A.D.) Nikomedia / Palestine Mint Host coin: DM T[Ib CONSTANTS PP], crowned facing bust cruciger & shield / M, ANNO left, cross above, [date] right, B below; NIK[O] in exergue. SB 440, DOC 27b. (?) (11.86 grams / 31 x 27 mm) Countermark: HRC cruciform monogram in 9 mm circle. Schulze HCM type 1b "Heraclian countermarks on Byzantine copper coins in seventh-century Syria" by Wolfgang Schulze, Ingrid Schulze and Wolfgang Leimenstoll - "During the military conflict between the Byzantine Empire and the Muslim Arabs in Syria in the years 633-36 Byzantine coins were countermarked by the Byzantine military with a Heraclius monogram. Countermarking most probably was exercised predominantly in Palestine I and was carried out to revalue the few circulating copper coins in order to remedy the general supply gap and disastrous shortage of cash." Quoted from a FORVM listing.
A relatively recent Leu auction fetched crazily low prices on Byzantine silver, so I came away with three. The first I've shown before, but I don't think I've shown the other two. The first is one of three known half-miliaresia (or 1/3 miliaresia) of Leo III: Dumbarton Oaks #23 and Sear 1512A. It weights only 0.76g. Plus I have been wanting a non-anonymous coin of Romanus IV of Manzikert fame, and ended up with two, a 2/3 miliaresion and a 1/3 with a portrait: Both holed... perhaps charms used by a resident of Anatolia desperate to ward off the Turkish invaders?
