Singapore overprinted 1997 5-dollar ship note from sheet

In January 2013, a contributor sent scans of two previously unlisted Singapore 5-dollar notes, possibily commemoratives overprinted on B21b (P35) at right front near the watermark.

The first note has a prefix of B/29 and is overprinted in red with 30 Anniversary and a small logo of the Board of Commissioners of Currency of Singapore (BCCS). It has a wide margin at left.

The second note has a prefix of B/35 and is overprinted in red with the logo of the BCCS.

From all indications, these notes were overprinted to commemorate the 30th anniversary of the founding of the BCCS, which would date them to 1997 or later.

According to another contributor, these notes were manually cut from sheets of notes and were not issued into circulation.
