2013 Topps Baseball Proven Mettle Visual Guide
Who says you need an autograph or jersey swatch to add value to a box? For the past few years, the flagship Topps baseball set has been using more and more manufactured relics to compliment traditional hits. In many cases, these enhanced inserts are bringing better returns for sellers and giving collectors something that's different in the process. 2013 Topps Baseball Proven Mettle is one such example.
Using a player coin as the card's centerpiece, these cards are big and carry some weight. The player's face is part of the coin. Each 2013 Topps Baseball Proven Mettle insert comes in three different versions: Copper (#/99), Wrought Iron (#/50) and Steel #/10).

The 25-card checklist includes has 13 current superstars and 12 Hall of Famers and future Hall of Famers. Some of the biggest names include Babe Ruth, Derek Jeter, Willie Mays, Ken Griffey Jr. and Lou Gehrig. When Joe Morgan, Cliff Lee and Joey Votto are the "lesser" names in a set, you know a checklist is strong.
That's one of the benefits of manufactured relics. Companies don't need to worry as much about varied costs and availability that come with autographs and game-used memorabilia. It also negates the need for redemptions (except in extreme circumstances).
Collectors have been responding by paying strong prices. Generally, these sorts of cards start at $10. Rarer versions of superstars can go into the hundreds.
Manufactured relics combine to fall one per 2013 Topps Series 1 Baseball hobby case and one per jumbo box.
The Proven Mettle set will continue 2013 Topps Series 2 Baseball.
