Important Warning
Restoration usually reduces collector value. Professional grading services label restored items, which can cut resale value by 30–60%. Always research before attempting any restoration.
CLEANING COINS ALMOST ALWAYS REDUCES VALUE. Professional conservation (not cleaning) by NCS is the only recommended approach. Never use abrasives, dips, or polishes on numismatic coins.

常见问题
修复是增加价值还是减少价值？
视情况而定。轻质、可逆的修复可以保值。大量修复通常会降低价值。
最好的修复材料是什么？
使用专为收藏品而不是家用产品设计的档案、双面材料。
我应该自己恢复贵重物品吗？
不，聘请专业人士。对贵重物品进行 DIY 修复通常会造成永久性损坏。
