These two items (150457138337 and 150457111106) are the second and third reported 1/4 oz Sino-Japanese Friendship medals I have ever seen. The first time I came across one was item #200481989085 which ended on June 13. All three sellers have zero feedback. All three sellers are supposedly located in the USA but when I sent a question about the weight of #200481989085 to seller aleexandera the response came from China. The seller assured me the medal had been weighed and is the stated weight.
A further concern is that items 150457111106 and 200481989085 use the exact same photo although the sellers have different accounts. I also note differences between the first numeral "1/4" in the photos of 200481989085 and 150457111106 and it seems to me that the lettering on the date side of 200481989085 and 150457111106 is not as clean as what I see on a known genuine medal of this year.
Finally, as far as I know 1987 Sino-Japanese Friendship medals were only struck in 1/20 oz. 1 oz. and 5 oz. gold sizes. I am extremely suspicious of these — either they are a never-reported size of medal or... Anyone else have some input?
