A comic is only worth what someone is willing to pay for it. With this in mind, CovrPrice only displays actual sales data (taken across multiple online marketplaces… not just eBay) to help you better determine the best value for your comics.
Our goal for this graph is to show overall sales trends for officially graded comics. Here we take the average for each condition and display it as a data point. To see the most recent sales data for each condition be sure to look at the individual sales data listed in the tables below. 8.1 trends in human population growth
“I sold a comic last week, why isn’t it showing up on your site?” | Engine | What changed | Impact |
At CovrPrice, we capture tens of thousands of sales DAILY. It’s simply impossible for a human to determine the authenticity of every sale coming our way. (Trust us, we’ve tried) To ensure the quality of our data we error on the side of caution, valuing accuracy over quantity. We only integrate sales for comics that our robots are confident are correct. While we don’t capture 100% of every sale in the market we’re getting closer and closer to that goal. If you think we missed a sale that you want to be entered into CovrPrice just contact us at [email protected] with information about the sale and our humans will investigate and add it for you. | Infant mortality collapses
That’s easy, when listing your comics for sale on 3rd party marketplaces be sure you include the following: Comic Title, Issue #, Issue Year, Variant Info (usually the cover artists last name), and Grade info.
For example Captain Marvel #1 (2015) - Hughes Variant - CGC 9.8
This will help our robots better identify and sort your sales more accurately.
×| Engine | What changed | Impact | |--------|--------------|--------| | | Shift from muscle to machines; better farming, transport, and sanitation. | Death rates plummet. | | Medical Revolution | Vaccines, antibiotics (penicillin, 1928), germ theory, clean water. | Infant mortality collapses. People live past 40. | | The Green Revolution | High-yield crops, synthetic fertilizer (Haber-Bosch process). | Food supply finally catches up. |
The Big Picture: A Hockey Stick for the Ages Imagine a graph that is flat for 99% of human history, then suddenly shoots up like a rocket. That is the story of our population. For millennia, growth was slower than a snail's pace. Then, in the last 200 years—a blink of an evolutionary eye—we exploded from 1 billion to over 8 billion.
| Still Growing | Already Shrinking | Plateauing | |---------------|-------------------|-------------| | Sub-Saharan Africa (will triple) | Eastern Europe, Japan, South Korea | China, USA, Western Europe | | High fertility, declining death rates. | Why? Low fertility, aging, emigration. | Why? Below-replacement fertility, offset by immigration. |
