Admin removed all of the square "proofs' because they are not actual proofs. They are considered the same as the "oversized proofs" found on ebay - simply items cut from the uncut sheets that were not cut to the proper size. In this case, since they were issued as discs, they should be cut down to discs. The squares are not eligible for listing.
