Hi Epiloque,
This may not be the answer you are looking for but I really do think you are seriously over thinking it and this should not be a problem and definitely should not be one that is consuming your time or thoughts. It really IMO is this simple buy and collect what you like and for whatever reason's you want to and don't take any notice nor care what anyone else says or thinks. This hobby or any hobby is meant to bring one pleasure and relaxation not stress and and anguish or IMO you are doing it wrong.
