To get some idea of what these are fetching I suggest you look on Ebay... for both your sixpences.... in SEARCH put 1944 sixpence... and after looking..... 1954 sixpence. You will find they are of very little value. Sorry if that's disappointing. Best wishes, Mike.
1964 six pence KM 903, looking at your I would say its worth about 30 cents maybe a bit more if you are lucky.
The Sixpence coins are considered good luck and are given to many a couple that are getting married or are newly-weds and seekers will usually pay a couple of Dollars or more to get them! I base this on experience as I have had some and without a price guide to go by, I asked potential buyers to make me an offer and they will usually give me $2 to $3 or more. Frank
Yes i said a coin of uncirculated would be £6 the coin here would be worth maybe a £1 i have 5 sixpences the earliest 1929 all metal detector finds
