Beer .5 ducat a pint.
College starting at 640 ducats a year up to 2560 ducats a year.
So formal education started at 1280 times and went up to 6400 times the price of a pint. Which at $6/pint today would be ~$7500 to $36k a year.
So that makes
1 penny = $40
1 crown = $200
1 shilling = $480
1 pound = $9600(they mostly have $4 and $4.50 price points, with some smaller batches costing more)
