A figure from a surprise egg is small, colourful, and usually a toy. A few motifs with a complete insert, or in the unopened capsule, reach prices in the collector trade that go beyond the sweets. I am not setting an auction record in the league of a watch here. In the overview Security for collectors this is the proof that the world reaches down to the small, and that protection has to follow the sum, not the aura.
How it leaves
A box of figures is a toy to most thieves. The few documented top pieces are still small and go out in the same drawer as other small stuff. You do not mix them with jewellery. Someone looking for the rare figure looks in collector circles, not in the police report from next door. Our radar does not name them.
What time does to them
Sun bleaches the colour. Plasticizer makes the plastic sticky. The insert creases and then is missing, and with it often the larger part of the price. Closed capsules stay closed. An opened figure and the insert sit together in a sleeve, dark, cool, not on the windowsill.
Where they go
As long as the sum is small, a quiet drawer, dark, and a list of the few expensive numbers is enough. If the sum grows into the range you want to insure, those numbers move into the safe, the insert as a copy into the document cabinet. The rest of childhood may stay visible.
