The brass plated steel 10 Pfenning from Germany is between the 10 and 20 cents, the brass 1 Centavo from Guatemala is between 15 and 25 cents. The 3rd British whatever coin it is looks beaten, so its probably worth the same as the first two, in best case scenario.
Cool old coins to add to your collection ! From a numismatic standpoint they are fairly common I believe. But these are fantastic finds for your personal collection. And as you already have them, something to build around. The trhird coin is a British Penny, first issued in that style in 1911. gary
