It really depends on the coins whether you should sell them as collector coins or as silver bullion. There are some coins with no value beyond silver value (for example, 1964 quarters/half dollars/dimes) and others that have value beyond silver only in nearly uncirculated condition, (for example, 1940s Mercury dimes), still other coins have value far beyond silver content even in a nearly unreadable coin (for example the 1916 D mercury dime). So it really just depends on the coins you have. In general, "retired" designs like mercury dimes, walking liberty half dollars, standing liberty quarters and Barber coinage goes for a higher premium than silver content. Though, this is not always the case as even some low-grade Barber coins have no value beyond silver. So it just really depends on what coins you have.

Sometimes a coin is so worn that you can't read the date. These coins are called junk, but if it is silver, it is still worth the silver weight.
The 7 silver coins in the set have a combined weight of 1.33823oz of pure silver
Silver coins minted before 1965 contained 90% silver with 10% copper. The coins' weights are as follows. Dime: 2.5 grams Quarter: 6.25 grams Half dollar: 12.5 grams Dollar: 26.73 grams To get the weight of just the silver, multiply those weights by 0.90.
With no rare dates they likely are only valued for the silver.
If you are interested only in the silver value, not all Halfcrowns were made from pure silver and the post 1947 coins contained no silver at all. Whatever the going rate for silver is. If you are interested in the collector (numismatic) value of the coins, please provide year and condition of the coins.
Whether you should purchase silver coins or silver bars depends on why you are purchasing silver. If you are a coin collector or want silver items that make a pleasing display, coins are probably preferable. If you are purchasing silver as a hedge against inflation, you may prefer bars, but may want to consider the security of where you will keep them.
