I think you’ve made a mistake here. The mintage of the US State Quarters has absolutely nothing to do with the demand for the coins. Because the US Treasury controls the mintage of circulating coins, the quantity of all cash instruments (from pennies to bills) is determined by the overall money supply needs of the economy.

So, when the government wants a tight money supply, they mint fewer quarters, and when they want to add money, they mint more.

That’s why the mintage spikes after the stock market crash – the government wanted to add liquidity and increased all cash instruments.

Actually, I wrote a blog post about how this might be a collecting opportunity. Because the mintage is controlled by the economy, it doesn’t really match to the demand for each state. If you assume that there is more demand for states with higher populations (since more potential collectors live there), it might make sense to buy up the quarters from big states with low mintages.

Check out my blog post (and eBay guide) on the topic. It’s the number 1 guide for state quarters on eBay now.
