I can see that there have been numerous discussions over the years - and probably ongoing - over token categorisation with many suggestions being made.
My question covers a very narrow sub-set of the topic, namely the UK tokens i have inherited. I can see a timeline that starts with 17C English trade tokens, continues with Conder tokens in the late 18Cand which then transitions to Currency tokens 179? to 1816). Each of these are Currencies within Coins for either United Kingdom or England.
By 1820 these 'currency tokens', mainly 1 farthing in "value" and certainly farthing in size, become Exonumia and are seemingly split between Trade Tokens > Business Tokens and Promotional > Advertising Token, even those with a 'value' quoted.
I am not suggesting that they should still be treated as Currency Tokens under Coins - but would not object - but are there any guidelines as to what is a Business Token and what is an Advertising Token. ?
For an idea, these are the current guidelines that are still under discussion and have not been published yet:
5.A. Business tokens Small-denomination tokens issued by private companies that circulated as a supplement to legal tender, being usually accepted only internally by the company or locally, by a selection of businesses. Commonly issued by cafés, restaurants, bakeries, merchants, pharmacies, banks, insurance companies, and other similar establishments.
Pub tokens or tavern tokens, bar tokens, or chits, used in drinking establishments. Wiki: Q7257252
American hard-times tokens: copper large or half cents, issued from circa 1833 to 1843 to serve as unofficial currency. They were issued privately during a time of political and financial crisis in the United States. Wiki: Q5655608

Feuchtwanger cents were private argentan tokens issued by Lewis Feuchtwanger during the 1830-1840s in the United States, in 1 and 3 cent denominations. The tokens were originally created as patterns and were temporarily used during economic depressions. Wiki: Q5446013
9.A. Advertising tokens Issued in support of a promotional or advertising commercial campaign. Often awarded for purchasing certain products. Sometimes issued in series of several types, intended to be collected and exchanged for a reward at the completion of the set.
Tokens issued to advertise a specific product or event should be called “Advertising token”
Tokens issued as part of a series of items intended to be collected should be called “Promotional token”
