nss-52 That "extra window" is difficult to evaluate from a picture alone. We are dealing with a transfer image (I am of the opinion that the coins were injection molded as are many Chinese fakes) and that process can produce some minor differences impression to impression. I can perhaps explain what I mean this way, if in the process of impressing the positive master copy of the coin into the plastic matrix that will become the mold, a small stray piece of the matrix may adhere to the positive image and then fall away on the next impression adding what looks like a window to that and only that image. Most injection molds have multiple images arrayed in a circle that is perfectly balanced so the metal spreads evenly. If I were doing this 4 or 6 coins would be easiest to produce per pour. The molds I have seen and worked with all had diameters under 14 inches.

The matching features are small raised dots on the die surfaces and arrangements of dentils (crowing or separation) that appear on each coin in the same places.

The 6 flaws were that there were 6 identical copies of the coin.

It is of course extremely difficult to find two or three well circulated 8Rs from the same die pair so 6 at one time was something special.

cableguy815 Yes it was!

I said reasons - not flaws. It pays to read the text as written not as you think it was written. It is the same way you have to read seller descriptions. Word for word.

I was having just a bit of fun since most sellers of forgeries only put them up one at a time.
