Find the value of different Maxx racing cards by using an online price guide such as the one available on TuffStuff.com, or by viewing listings on an auction site such as eBay.com. Alternatively, look up the value of a specific racer's card on sites such as Beckett.com, PSACard.com or CardboardConnection.com.
Many sports collectibles websites publish free pricing guides for various styles of items, including Maxx racing cards. TuffStuff.com contains a free downloadable PDF valuation guide that covers numerous racers and cards, though the site may not update the guide on a regular basis. Sites such as Beckett.com offer annual price guide services for a subscription. This service allows the purchaser to check the value of specific cards in different years, with access to the guide limited by the subscription model.
Another common way to check the prices of Maxx racing cards is to visit an auction site such as eBay.com and check the current list prices for cards. Look for sellers with an established rating and sales history to identify business or individuals with the strongest understanding of the current market values. These sellers likely consult their own value guides before posting, and thus set their prices according to the latest trends.
