is it possible to change the currency rate to US to Canadian ?

Your software is updated, how many times per year?
Are the updates free?

ok ,

Merci pour information ! 

Do you plan to develop your application for linux someday?

Paper money and coin

Thanks for the information.
I admit that I am lost!
For example, let's take a 1963 Canadian standard VF-20.
The value on a Canadian WEB site (updated on March 25, 2019) is $ 0.03.
In a Canadian currency book edition 2019 .. $ 0.01. in your software (by the way it's great) with the exchange rate of $ 1.33 the value of the same pieces is $ 0.13

Do you have an explanation for me?

Do you have an American website or could I validate the value of my Canadian pieces?
Thanks in advance

why the value of the corners is very different with this website http://www.numicanada.com/index.php and

this book http://www.coinsandcanada.com/shop-coinsandcanada.php?category=books-and- catalogs & cat = 1 & item = 80

I download e demo coin and paper money Canada. the value to display is in Canadian Dollard or us ?
If it is in us is it possible to change it for Canadian $
If yes, how ?

Merci
