Little Grogg version of Shane Williams worth £1,500
A unique Shane Williams Grogg made for a charity auction is believed to be the most expensive, selling for £1,500.
The figures are made by one man in Pontypridd.
However, it is those no longer made or one-offs produced for charity that change hands for large sums on the internet or can be picked up cheaply at car boot sales.
Collector Anne Danks from Monmouthshire paid £1,500 for the only Shane Williams produced in his Japanese club colours, in an auction for Velindre cancer centre in Cardiff.
