Silver cigarette cases

I just got this 3 cigarette cases that i love in terms of detail , i think they are from Hong-Kong from around 1920 , is this correct ? The one with the wood inside weighs 248,7 gr and measures 122mm long and 50 mm height , the one with the 2 side´s opening has 177 gr and measures 128 mm , the smallest one has 112,4 gr and measures 94 mm.Any idea hoe much they are worth.Here are some photo´s.Thank you.
