The value of money from one decade to another is a very confusing topic - in my opinion, anyway.
For instance, something called the CPI Inflation Calculator states that $1 in 1800 was the equivalent of $19.98 today. Check it out:

And yet the daily wages of, say, an artisan, was about $1, according to this:

... which, according to the information on some websites, would have bought him four pounds of coffee or three gallons of whiskey.
According to the TV comedy Honeymooners, a bus driver working in New York made $40 per week in the 1950's. The Inflation Calculator I mentioned earlier claims that in 1955, $1 was the equivalent of $9.39, which would make a New York City bus driver's wages less than $400 a week before taxes.
Like I said, this is all very confusing.
Now, my question is:
In the year 1800, how much would an affluent lady pay a New England prison warden in order to be allowed to see her lover in private and out of turn?
