Help w/ID Hammered Metal Cups Marked Denmark

hi everyone. i found these yesterday and have not been able to find this mark anywhere online. I'm really not sure what the metal composition of these cups is. they don't really look like silver, but they don't look like pewter either. they stand just under 3 inches in height. none of the cups have a very strong, easily read stamp on the base. i've provided the best pictures i can of the art. i think if you look at all three images of the marks you can get a pretty good sense of it. i would really like to figure out who made them and possibly when. any help will be greatly appreciated...thanks
