Memorabilia vs Cards and trends...

[Butch7999]

The question, as posed, seems to us too impossibly broad to answer. If it were asked whether card prices
were rising, falling, or stable, the answer might be different for 19th-century cards versus post-war vintage,
or T206s versus modern shiny gimmicks. Similarly, does "memorabilia" mean everything under the sun,
or only autographs, or only photographs, or game-worn uniforms, or bobbleheads, or stadium seats,
or trophies, or... or... or...
Each genre, each niche, seems to have its own set of collectors, and its own market fluctuations,
prices rising, falling, spiking, sinking, usually returning to some more typical level.
Or maybe we misunderstand the question.
Just sayin'.
