Mexican silver hat figurine. Likely has the maker's initials and a 925 stamp. Weight: 20 grams. Cufflinks with silver stamp, weight: 16 grams, with stones. Ring with "USA" and silver 925 stamp, weight: 2g. Total weight: 37 grams. Since this is for home use, I think there might be a little more. Although the price exceeds 600 yen per gram, I'm calculating it at 500 yen. Moreover, it might be someone's work, so it's a good deal.
