Can You Date "Good For" Tokens By The Good For Value?

Generally speaking, I say, "no." For example, I've seen some western tokens, bearing a face value of 12 1/2 cents, that date well into the 20th century. Beyond the denomination, a number of factors come into play when estimating a token's date/era. The token's metal content, use and style must also be considered. The more tokens a collector sees and studies, the closer he can come to dating them. That said, we can all err at times.

I would agree with Exo as well. One would have to consider what was being sold as a promotion. A coat would be a much larger discount than a penny cigar for instance.
