Fortunately, the resolution of pictures at StacksBrowers website are excellent and pictures can be cropped and enlarged to see the details. Attached are another enlarged section. 1996 bimetallic unicorn shows many extra materials in the crevices of Chinese characters and number VS. 1995 (second picture). Clearly, the production die of this coin was copied from a coin not from a master die. The lighting may effect the picture. IMO, the differences are not all caused by the lighting.
The bidder may be able to examine the coin closely by looking into the displace box. However, the detail differences and defects can not be detected without a high power magnifier.
