Die Markers ?

[Rollem]

I recently posted a '99 die clash and since then from other '99 coins with some of the same was curious to know if they may be from same die.

Photos 1&2 are first coin.. 3&4 next and 5&6 last.

Photo of second reverse shows signs of obverse in 'states of ' and a weak reverse minting of states' in this same bag I have found a half dozen coins like this weak mint on states of. Could this be caused by the clash or is this common for '99p.

Where would one began to ID. a particular Die?

Last two photos are just my most recent Die Crack on memorial, and maybe brownie?

To determine if two or more coins are from the same die you need one or more die markers (gouges, dents, die scratches, clash marks) which are in the identical positions.

The '99s have a lot of clash marks on the reverses, so they could be the same or all different - hard to guess. STATES of is frequently weak on memorials period and, in my opinion, is a likely place for grease to gravitate to thus making it appear weak.
