No problem to get the 'gold value' in Canada, where the Bank of Nova Scotia will take them based on gold value.

Collectors want excellent condition, and rare dates or markings; otherwise the value is little more than the gold value.

Your library, if large, may have catalogues, issued yearly, that list values by date and condition. Catalogues cost about $15-30; Spink's Coins of England is 17.70 pounds.
