text: As mother coins (母錢) were used to cast these coins which were always exact it indicates that these "flower holes" were added post-casting, the largest amount of known cash coins with "flower holes" have very prominent octagonal holes in the middle on both sides of the coin, comparatively their legends are usually as defined as they appear on "normal cash coins", for this reason the hypothesis that they were accidentally added is disproven.
