After NOPSI went to an exact fare system, and conductors and bus drivers no longer made change, tokens were advertised as an alternative to the nuisance of presenting exact cash fares.  Banks, grocery stores, and many other kinds of stores sold the tokens in packets of 10 or 20, although the price per token was still the same as the cash fare (15 cents at this time).  The tokens seen in Pictures 21B-2 and 21B-3 were the ones usually included in these packets, but an occasional older token (Picture 21B-1) could also be found. — Collection of Earl Hampton
