Perhaps Royal Copenhagen? This is a set of 5 plates with the alphabet "H" on them. The mark looks like Royal Copenhagen, and the "H" appears the same, but I cannot guarantee it as I don't have information about when they were purchased. These are used items, but there are no noticeable stains or chips, and I think they are in overall good condition. Please refer to the images for more details on the condition. I am decluttering my home. When shipping, I will carefully pack them using cushioning material, but I cannot guarantee against breakage. Thank you for your understanding.
