I only have four Carolingian coins so far (on account they are usually pricey) but I wanted to make a coin collage like those I've seen here and elsewhere, so I thought that this would be an easy one to make, since, like I said there's only four coins, and also because all of them have almost the same kind of background.

Both coins in the first row and the first of the second row are deniers of Louis the Pious (Charlemagne's son), and the second coin of the second row is an obol of Charles the Bald (Louis's son). Clockwise the mints are Metallum, unknown, Metallum (Metvllo on the coin), and Venice (which, oddly enough wasn't officially a Frankish city but made Carolingian coins anyways).
