♪(ᴖ◡ᴖ)♪ Adding images now. My son took the 18K hollow necklace chain (41cm, approx. 4g) out of the time capsule box, removed the white jade pendant top, and put it on this top, and it looked just right. So, I'll list the white jade pendant top separately. ヽ(￣д￣;)ノ=3=3=3 There's something shiny and heavy in the time capsule box! d(^_^o)… You found it! d(^_^o) This is a pendant top made with an 18K (k18) frame around the largest coin (gold coin) that was actually used for shopping in the old days in America. o(^▽^)o… Then you could buy ice cream! ٩( ᐛ )و… Ice cream... ( T_T)＼(^-^ ) You might not be able to buy it in Japan... ( T_T)＼(^-^ ) Then it's useless... You're right... (//∇//)… Something's not right... d(^_^o) That's how the conversation went... o(^▽^)o This pendant top is... (*^o^*) From the United States of America, 1923, ( ´ ▽ ` ) 102 years ago, the largest gold coin (33.44 grams, 90% purity (k21.5٩( ᐛ )و21.5K, I guess?)) with an 18K (k18) frame (=^▽^)σ and chain, 10 grams. A gold coin necklace weighing 43.5 grams in total. (=^▽^)σ However, as those in the know will understand, This month, ♪(ᴖ◡ᴖ)♪ the 20-dollar gold coin currently being auctioned in the Japanese coin auction is a high-relief type, which has a deeper engraving than usual during the manufacturing stage, and is a different type from the rare coin type that enthusiasts long for, so the price is also different. ♪(ᴖ◡ᴖ)♪ Don't misunderstand! I'll explain it properly... ( ˘ω˘ )… I used to have 20-dollar gold coins from the early days, 1851 and 1905, but they're sold out now... (//∇//)… gone. ♪(ᴖ◡ᴖ)♪ I used to be a gold coin collector. (//∇//)… It's super heavy, so it's the perfect pendant top for those who like stiff shoulders♪ ψ(｀∇´)ψ Gold prices are still rising, and I think it will become more and more of an investment target, so if you want to buy it, do so now. However, |(￣3￣)| it's guaranteed to be genuine, and the images and descriptions of the weight are accurate, so it's a no-claims, no-returns sale to prevent swapping.
