Glasgow Corporation Transport has issued two varieties of the 2d black token, the normal type with the small CoA and another with a larger shield to the CoA and a much wider spaced legend. It is in fact a different CoA.
The reverse of the second piece has a slightly smaller 2d denomination. They measure 22.2mm and 22mm respectively.
I would imagine the possibility exists to find similar varieties in other values from Glasgow.
Added ½ penny blue-green, 1-½ d yellow, 3 d red and 4 d pink. The threppence looks like it was produced with a different technology. The D has no full stop. Figleaf
