This silver half groat (Medieval English coin) was issued under Henry VI. On the obverse is a crowned bust (probably Henry VI himself) and on the reverse is a cross. The coin was not only clipped but at some point folded, breaking upon unfolding.
This folio comes from another Kufic Quran. Notice the abundant red dots and black tick marks indicating vowels, and the odd diagonal slant of the text as a whole.
Pictured here is a page out of the famous Blue Quran, which is dispersed all around the world and which the Harvard Art Museum is lucky to have a fragment of. The gold text is also in the Kufic style.
