Based on the average inflation rate of 1.4% p.a.since independence and starting from 1787 when the first cent was minted giving two cents worth is a little over $50 today.

According to Snopes, it dates back to mid 1920’s. Another site says March 1926.

That comes out to about $0.29 in 2018?

@raum is correct—it was never supposed to be more than a minimal contributed amount. Just enough to tip or balance the scale.
