As a general rule, do alblum toned coins tend to tone from the rims inward? Does it happen on both

Thanks, this is an off shoot from another thread about putting BU coins in alblums.

generally speaking also, if it's an album w/ slides (dansco, wayte-raymond), obv. & rev. will tone simultaneously & in sync. if it's an old-style whitman coin board, the rev. will tone much more then the obv., or at least the side facing the back of the album will tone the most. in some cases, the rev. will corrode while the obv. will be just fine.
i'm telling you this based on 35 years of experience using albums.

this is a tricky question not easily answered with a quick two word post, right Jeremy??
it seems that maybe thirty-five years ago, to use DK's number, storing coins in albums was a normal and accepted way of housing a collection. i wonder how often those collectors pulled out their folders and were dismayed to find the BU coins starting to "turn" and subsequently cleaned them in some fashion, thus damaging them. others left them as is and we have some wonderful toned examples today.
fast forward to a time when it's known what agents are harming coin surfaces and manufactureres are striving to eliminate those chemicals from their products. AT/NT issues cast a dark shadow on the hobby. now enterprising collectors are clamoring for old style, chemically treated storage folders to place coins in, with the hope of duplicating the past, right in line with the retro-movement that swept the late 90's.
for me it always come down to intent, although noone can really differentiate between the coins surface from the two scenarios. placing a coin in an environment which is known to be damaging to it's surface with the hope of imparting attractive tone to enhance it's value just seems blatantly AT to me. but that's just me.

Even purists view album toning as NT, because the albums inadvertantly caused the toning. The intent of the album was always to store and protect the coins, but as we now know, many of the albums cause toning.

not true. MANY coins from albums would & do consistently get body-bagged for "artificial toning".
purists would define "natural toning" as toning that occurs as a result of exposure to a coin's natural environment, which most of the time is CIRCULATION. bank rolls, bank bags & vaults, etc. might also be a natural environment for certain coins, but the mint most certainly did not manufacture bust halves with the intent of storing them in cardboard albums.
