The Royal Mint advises that the undated 20 Pence coin is legal tender, so they are possibly not treating them any differently to any other coin.
There were less than 250,000 released into circulation, the majority of which would now be in the hands of coin collectors, coin dealers or collectors of curiosities.
No. The new design coins introduced in 2008, have the date on the "heads" side.
There were sufficient 20 Pence coins in circulation already. Some 1986 20 pence coins were issued as part of Royal Mint sets, but these were Proof FDC coins not for general circulation.

See the link below to the Royal Mint.
In 2008, all British circulating coins had a redesigned reverse. When one of each of the six "Pence" coins is arranged correctly, the composite design shows the Royal Shield. That part of the shield visible on the 2 Pence coin shows the "Lion Rampant" from the Royal Banner of Scotland.
