REPLIES TO NUMISMATIC QUERIES.
I beg to offer the following remarks in reply to the numismatic queries of E. S. T. (Vol. i., p. 468.):—
1. I can only account for the Macedonian coin being struck in lead, by supposing it to be the work of an ancient forger.
2. Third brass coins of Tiberius are not uncommon; I have one in my cabinet of the sort described. Obv. head of Tiberius, TI. CAESAR. DIVI. AVG. F. AVGVSTVS; Rev. the altar of Lyons, ROM. ET. AVG.
3. The coin of Herennia Etruscilla is probably a base or plated denarius, the silver having been worn off. Silver coins sometimes acquire a black tarnish, so that they are not to be distinguished from brass without filing the edge, or steeping them in acid. If a genuine brass coin, it should have the S. C. for Senatus Consultum.
4. The coin of Macrinus was struck at Antioch in Syria, of which famous city there exists a regular series of imperial coins from Augustus to Valerian. One in my possession has Δ above the S. C., and Ε below for ΔΗΜΑΡΧ. ΕΞΟΥΣΙΑΣ, Tribunitia Potestate. May not these be the letters described by E. S. T. as L. C.?

Coins of Constantius II.—Can any numismatist kindly inform me by what marks the coins of Constantius II., the son of Constantine the Great, are distinguished from those of Constantius Gallus, his nephew? Mr. Akerman, in his Rare and Inedited Roman Coins, gives the following titles as common to both, but does not afford any rule for appropriating their coins:—
CONSTANTIVS. NOB. CAES.
FL. IVL. CONSTANTIVS. NOB. CAES.
D. N. CONSTANTIVS. NOB. C.
D. N. CONSTANTIVS. NOB. CAES.
