I found this currency converter today, and you might find some use for it. It will convert 2005 currency to most any decade starting with 1270.

So, if I plug in £45,000 from 2005, I get 84 pounds, 9 shillings and 5 old pennies for 1270. It also breaks that down into 8,447 craftsmen days, 649 stone of wool, 527 quarters of wheat, 241 cows, or 111 horses. It's interesting to see that the value stays pretty close throughout the middle ages, but it does spike up to 134 pounds in 1320.

Looks like a useful tool. Thanks!

This is great i don't know if i'll ever use it in my pendragon campaign but stuff like this is always fun to poke around with.

One thing to keep in mind that the Pendragon £ doesn't match the historical £ exactly, either.

For instance, a gambeson armor (padded, quilt armor that would be the more historical analogue of the 'leather armor') could cost closer to £1 instead of 15d.

In 1344, an income of £5 meant that you were supposed to provide an archer for the King's army (in England), and £25 meant a man-at-arms (roughly equivalent to Pendragon's mounted mercenary sergeant).

The richest noblemen during the War of the Roses (15th century) had income in the £5000 range, compared to £1000 - £1500 that the richest have in WARLORD (granted, this is Uther's time, more closely aligned to early 12th century).

Just something to keep in mind. :)
