1971 proof pence

Hello i have a set of coins from UK it is a proof set but some of the dates are completed and dont show the 1971 proof. so the ones i have are regular strike or numista is missing the proof coin from this year?
This one doesnt show the 1971 proof and it says that the year list is complete https://en.numista.com/catalogue/pieces878.html
Thank you for your help.

It's quite genuine.

The Royal Mint is selling this set through this URL:

Thank you Matt my other question is that numista doesn't have some of this coins listed as proof (proof doesn't exist for that year) should I just put them in the regular strike or are they different?
