South African Inventions – Retinal Cryoprobe: 2 1/2c (Tickey, Sterling Silver) 2020
The reverse of the tickey depicts a gloved hand holding the retinal cryoprobe, the letters ‘SPA’ for ‘Selig Percy Amoils’, and the denomination 2½c.
When the tickey is placed onto the circle on the crown, it gives the impression of a retinal cryoprobe procedure.
