Are there any valuable 2 pence coins?

Answer 1

No. For every year they have been minted, they have been minted in huge quantities, so they are neither rare nor valuable.

The best you might get for an uncirculated Proof FDC coin might be £2 GBP.

The 1983 2 Pence coin inadvertently had the word "NEW" stamped on them due to selection of the incorrect die at the Mint. These coins are very collectible, if not valuable, but were only included in some Mint Sets packaged by the Royal Mint.

For a few months in 1998, 2 Pence coins were minted from bronze.

These coins are still potentially in circulation so, unless they are part of a Proof or uncirculated mint set or are individual Proof or uncirculated coins and in absolute mint condition, they are worth Two Pence.

Answer 2

Of course, and there are too many varieties to list here for valuable shillings since the coin was produced for several hundred years!

Basically anything dated 1920-1946 will be 50% silver and worth a bit in silver regardless of the condition.

Anything dated prior to 1920 will be sterling (92.5%) silver and worth silver melt regardless of the condition.

Anything dated 1947 or later is copper-nickel and as such has no melt value.

For post-1946 coins, the 1959 Scottish Reverse shilling is worth a decent amount.

Of course there are many different varieties of even copper-nickel shillings, far too many to post here. Your best bet of getting an answer for an individual year is to post a question including the year of issue. Or by purchasing a British coin guidebook such as The Standard Catalogue of English Coins, published by Spink and Son.
