Just look for a stamp store… give them a call
I think you only need 1 or 2 however you can always get more to share
They should be cheap, unused, pound, pence or shilling denomination too

@carolvolk OK focusing on getting these stamps in Toronto (stamp store) or online. Pre decimal means it is a pound OR shilling not a pound and a shilling? for example using the Canadian currendy, $1 and not $1.40. So not available for Canadian stamps? They will have pound, pence or shilling? And they must be unused.

@carolvolk Found this place and they have a lot of pre decimal stamps https://centurystamps.com/ I am going to visit there soon. They will deliver but they need a list. Since I am learning, i need to go there to explore more and find out about what is available. He said that they are pre 60s/70s before they converted to the decimal system. Will keep you posted.

@cherylmillett sounds good - I have many... and I do not think you have to worry about a denomination
