High end collecting is about quality, not the 
price. 

All things being equal, the highest quality 
artwork maintains the best value and liquidity. 
Lower quality artwork falls faster and takes 
longer for prices to recover, if ever. 

Just look at dealer inventories. Low quality cels 
stay on the shelves forever and mid-quality cels 
take a long time to move. However, high grade 
cels are snatched up immediately regardless of 
the premium. 

You cannot determine quality by price unless it's 
for a specific series. But knowing that, high 
quality and low quality can both be found below 
and above your arbitrary price point.
