Perhaps tokens will outlast coins. We live in an increasingly cashless society. I rarely use cash now as virtually all payments are contactless. It does not seem that long ago that shops would not take cheques for payments under a certain amount. In some places you had to get a cheque verified first before it would be accepted. Credit cards were for the rich and for large amounts. The there was “your flexible friend”. I wonder what happened to him.
The idea of a token in the senses of a voucher that has a fixed value and can only be spent or used for one thing is still popular. This includes machine tokens, car park tokens and vouchers for food. One thing cash is used for is beggars although I have heard of then sometimes taking card payment. ( I am serious and I do not belittle people who are genuinely desperate). Perhaps tokens could be issued to give to people in need that could only be spent necessaries.
When I lived in the West Midlands the collectors I knew all collected local tokens. I could never see the attraction in pub and trade tokens. Looking back I think I get it. Tokens give an insight into life, usually on a local level. They are usually connected with need as cash is the prerogative of the wealthy.
