Would be useful to see the other side of the coins instead of two views of the obverses. Matching dates make a difference to the value, and if they don't match then they are better sold individually. The holed one is never going to be worth much. The threepence and fourpence are collected even by non-Maundy collectors.
Well the threepence and the fourpence look to be 1705, but the twopence looks more like 1703. The One penny I can't really tell, but with the hole that is the least collectable anyway. Not really saleable as a set because of the differing dates and the damage to the one penny. The 1705 Fourpence is actually a scarcer date for that denomination. Spink 2018 gives £40 for the 4D, £18 for the 3D, £22 for the 2D all in fine condition. I hope that helps.
