Your day will come @Momof4. Just hang in there and keep educating yourself, but go easy on yourself for the "maybes" you find. We all started some place. It's takes a lot of patience and time.
Well, except that she asked specifically about the supposed Wexler's "die markers". Die markers don't move, that's what makes them markers (exactly). So you may (could) infer that a particular coin has doubling (which would be exactly the same on every coin struck from that die) even if it has been obliterated, because of the exact positioning of any specified markers. For example, it's akin to inferring/determining that a 1864 Indian Head cent is an "L", even though the "L" has been obliterated, by being able to discern whether it has the "pointed bust" or the "round bust". Just sayin'
...and I hear ya “sayin’”...so yeah, it’s a doubled die if the markers are exact, but hard to get excited if the doubling itself is worn away...Spark
