Although described as regular dies trial pieces, these were actually deliberately struck for sale to collectors as part of complete off-metal sets.

Examples were struck as follows:

Copper J1176/P1318 with fewer than a half dozen known.

Aluminum J1177/P1319 with only 2 or 3 known.

Nickel J1178/P1320 with only the former Farouk coin believed to exist.
