https://cuds-on-coins.com/spike-head/Heres some general info:
They're technically not an error or variety, but caused by the aging dies as Mike Diamond has mentioned. Generally die cracks on circulated coins are common because of the high volume made these days so more get out of the mint, and so it was thought that they would rarely elicit any significant collector interest or value due to being common. "Spike head die crack is a sub-category of a die crack commonly referred to as a "spiked head." Though they can be found on most denominations, they are primarily collected on the
Lincoln Cent." - CONECA So these spike heads are popular to those who also collect errors and varieties, and some like to collect them so they do have added value. Ken Potter mentioned "I believe that die cracks on proof dies are routine, but that coins from them escaping the Mint were not common in the past." and then it seems from reading the rest that due to the increased volume production and new ways of monitoring and not rejecting them, they are becoming more common. Further many more people are looking/collecting these type of things today than the past so more are turning up for sale keeping the values down.
From Ken Potter:
A die crack that runs from the head to the rim of a coin is often referred to as a Spiked Head and given more attention than die cracks found in other areas. However, any prominent major die crack on a proof coin is considered collectible as they are rarely encountered, though more have been showing up in the recent years then ever before. I believe that die cracks on proof dies are routine, but that coins from them escaping the Mint were not common in the past. One cause may be the great increase in coinage production since the inception of the
State Quarter program and other programs that followed. This greater demand for production appears as though it may have taken its toll and resulted in more errors of this type escaping the watchful eye of the Mint. I'd like to stress the fact that die cracks on general business strike coins made for circulation are exceedingly common and rarely elicit any significant collector interest or value. They are the norm and rarely considered errors by this observer. The
Washington quarter portrait has always been particularly prone to die cracking since its inception in 1932.
