I can relate to you, silver coins do have its own charm and yes, they are addicting. Ever since I started collecting in 2018, most of them are in silver/copper-silver now. I think it's because I rarely feel guilty buying them due to their composition and most (not all though, but more likely) silver coins have more decorated design compared to other coins made out of lesser metal (such as copper/nickel) internationally. I have seen your collections and those are marvelous, you should try collecting circulated coins sometimes, some of them might be your next target to collect as they might have even grander design and history with them
