钱币包浆自然，底光柔和，所谓包浆是自然形成的氧化层，也有人为手盘包浆，两者不同，但同时都有保护钱币的功能，有如给钱币镀上一层保护膜，使钱币不再氧化，便于收藏传世，如果觉得钱币脏，可以用清水洗，再用棉布擦干，不要破坏包浆，破坏了包浆就相当于破坏了保护层，更重要的是包浆是鉴定新老钱币最简单有效的方法。细看钱币品相完美，没有磕缺，损毁，变形等是不可多得的收藏级铜钱，建议收藏，传世。

我国青铜剑的创造及其发展历史，约可追溯到原始社会开始进入奴隶制社会的商周时代即已出现，发展到春秋战国时期已是高峰阶段，嗣后，一直延续到秦汉。

直到铁剑出现时，青铜剑就逐渐销声匿迹了。通过田野考古发掘，全国各地出土包括青铜剑在内的青铜兵器，可说是层出不穷，异彩纷呈，特别是前些年，吴王夫差剑和越王勾践剑的发现，更是震惊中外，成为稀世之宝。

旋纹圆柄青铜剑

青铜剑也是有着规格的不同，此剑与越王勾践剑一个级别，同是圆柄，并带有旋纹，更易握紧，属于将才使用的青铜剑，等级规格较高，剑身红斑绿锈，表现开门，中心有一棱筋直通剑首，造型古朴而优美。

东周时期盛行佩剑之风，在剑上集中了多项杰出的装饰技术，其中位于青铜剑首端部的同心圆装饰以其精湛的制作技术引起了科技史界的关注。

青铜剑在技击格斗中，首要功能是刺杀敌人、穿透对方的铠甲，劈砍、划拉只是辅助功能而居于其次。在青铜时代，铸剑的关键是在冶炼时，向铜里加入多少锡。锡少了，剑太软；锡多了，剑硬，但容易折断。对秦剑做的化学定量分析显示：它的铜锡配比让青铜剑的硬度和韧性结合得恰到好处。作为是青铜剑铸造工艺的最后巅峰，秦剑的长度、硬度和韧性达到了几乎完美的结合，攻击性能也因此大大增加，此剑虽历史悠久，仍可见其锋芒，整体品相完美，具有极高的收藏价值。

The creation and development history of bronze jian in China can be traced back to the shang and Zhou dynasties when the primitive society entered the slavery society. It reached its peak stage in the Spring and Autumn and warring States periods, and continued to the Qin and Han dynasties later.

Until the appearance of the iron sword, bronze sword gradually disappeared. Through field archaeological excavations, bronze weapons, including bronze swords, have been unearthed all over the country, which emerge in endless succession and are of great color. In particular, some years ago, the discovery of Fuchai swords of King Wu and Goujian swords of King Yue shocked both home and abroad, becoming rare treasures.

Bronze sword with circular handle

Bronze jian also has different specifications, this jian is the same level as Gou Jian jian of King Yue, with round handle and spiral lines, which makes it easier to grip, belonging to bronze jian used by generals, with higher specifications, red and green rust on the body, which shows open door, and a rib in the center connects to the head, with simple and beautiful shape.

In the Eastern Zhou Dynasty, the trend of sword wearing prevailed, and many outstanding decoration techniques were concentrated on the sword, among which the concentric circle decoration located at the end of the head of the bronze sword attracted the attention of the scientific and technological history due to its exquisite production technology.

In the fighting, the primary function of bronze sword is to stab the enemy and Pierce the armor of the opponent, while the secondary function is chopping and pulling. The key to making a sword in the Bronze Age was how much tin was added to the copper when it was smelted. Tin is low, the sword is too soft; Tin, hard sword, but easy to break. Quantitative chemical analysis of Qin jian shows that the ratio of copper and tin makes the hardness and toughness of bronze jian just right. As the last peak of bronze jian casting technology, Qin Jian achieved almost perfect combination of length, hardness and toughness, thus greatly increasing its attack performance. Although this jian has a long history, its edge is still visible, its overall appearance is perfect, and it has a high collection value.
