[QUOTE="TIF, post: 3164564, member: 56859"]I have to disagree about the "Tiber" or "river" patinas. The term does not connote a [I]lack[/I] of patina. Orichalcum is a brass alloy. Original surfaces and original surfaces would be gold in color and reflection, something like these tumbled brass blanks: [ATTACH=full]813200[/ATTACH] Freshly struck orichalcum coins would likely have resembled these tumbled brass blanks. Brass forms a patina which looks like this and which resembles the "Tiber patina".
