Interesting coin the 5 shilling piece the old age pension was introduced in about 1905 or 6 and all over seventies got five shillings (A crown) to live on .
Over the years inflation increased its value to approx. where the old age pension is now £200 .Almost a eight hundred percent increase
Funny enough £200 was about the amount I paid for the coin about a year ago , it might fetch £250 now if i was lucky.
Lots of strange coincidences there though.
