I need help with difference between Bhutan 1/2 Rupee KM# 26 and KM# 28.1

km#26: N#30856

km28.1: N#9170

With the first coin having : “Weight varies: 5.78-5.90 grams.” and the second one having 5.85 grams i can't differentiate by weight.

They have same diameter.

While the second one has a nice detailed picture, the first one seems a bit worn and smaller low resolution picture to me it looks identical.

What exactly are the differences between the two ?

If anyone has the km#26, could you help with a hi res picture of both faces ?

The NGC reverse on the km#26 has a different legend than the one on numista.

Thx !

NCG has a correct picture for KM# 26, Numista has an incorrect image. I'll submit a request to remove the image.

Another difference on the reverse is the NGC coin has more space between the images and the edge. The lower left was the first thing that jumped out to me.

The difference in the legends includes the date (probably ruler as well). KM# 26 is CD 5 (called “(1928)” by Krause). KM 28.1 and 28.2 are CD 17 (called “(1950)” by Krause).
