I sadly do not have access to a scale, but its diameter (26-27mm) fits with the as.

The problem here is size, and your earlier description of diameter is inconsistent. Your obverse measure is the size of 41/e, but your reverse measurement is consistent with 56/3. How did you measure the diameter? If you have a caliper graduated in mm, try taking two readings from the outside edge, one at the widest separation across the coin, the other at the smallest. If it is truly round, take measurements that differ by 90degrees of rotation. Please give us those numbers.

My very first measurements on Christmas Eve were approximate and not accurate. The second measurements are accurate. I only have access to a ruler, and the rim is not vertical or straight but rather graduated or slanted, growing slightly more narrow from obverse to reverse:
On the reverse, from 12 o'clock (top of S) to 6 o'clock, I measured 27mm; from 9 o'clock (rear of ship) to 3 o'clock, I measured 26mm. Both measurements were taken from the top of the slant, as indicated approximately by the red line:
On the obverse, from 12 o'clock (top of bust) to 6 o'clock, I measured 29mm; from 9 o'clock (left of bust) to 3 o'clock, I measured just a hair over 29mm. Both measurements were taken from the bottom of slant, as indicated approximately by the red line:
I hope that helps!
