GB-1993-20-P-Die-Adjustment-Piece?

Found this in a bag of UK coins and tokens. There were also some planchets for this period's 1p, 2p, 59p, 10p, and 50P coins.

This may be a die adjustment piece. It has near full weight (4.89 grams vs. spec of 5.09 grams). Any comments?

A die adjustment strike is a type of mint error coin where the devices on the coin are struck improperly because the strike was made while a die setter was adjusting the coin press machine. When the coin press is being set up to strike coins, some test coins are struck to determine the optimum striking pressure before the coin press is turned over to the press operator for regular coining.

These test strikes are supposed to be carefully collected and destroyed, but on rare occasions they escape the mint.

Die adjustment strike specimens usually appear as weakly struck to very weakly struck specimens, although sometimes a die adjustment strike can be too hard. Both types of die adjustment coins are sought after by error coins collectors.

What strikes me as most interesting is that it is a twenty pence but it seems to be on a round flan. It should be 7 sided... surely even a test piece would use the right blank?
