双旗币 产生于民国时期，民国在中国上仅仅存在了几十年的时间，这几十年时间里中国内外战乱不断，因此，在兵荒马乱的年代，钱币在经历了无穷的岁月之后，依然可以完整地保留下来，实属不易。保存完好，钱文、图案清晰，流通痕迹明显，包浆自然，铜色透亮。
因为双旗币产生于民国时期，民国在中国历史上仅仅存在了几十年的时间，钱币在阅历了无量的岁月之后，仍然能够完好地保留下来，实属不易，具有很高的文物保藏价值、历史文化价值以及艺术品鉴价值。虽然民国时期的钱币版别较多，但也在当今的藏品市场中并不多见。
湖南省双旗币
正面呈双圈，外圈上置楷书‘湖南省造’四字，下置楷书当制钱二十文币值，左右各一荷花纹，内圈双旗一边的铁血十八星旗的外形采用了树叶状，另一面的五色条旗上的条纹可能受到当时军阀纪念币的影响而变得考究起来了：呈波浪状线条，双旗交叉处顶置芙蓉花。
反面呈双圈，外圈英文THE REPUBLIC OF CHINA TEN CASH，内圈中置稻穗组成的嘉禾纹，表面包浆，使得钱币如有穿上一层外衣保护着钱币，锈迹有明显的颗粒感，为真品无疑，有包浆的钱币几乎不再氧化能更好的收藏保存，而且目前包浆是无法仿制的，也是鉴定新老钱币的捷径。
双旗币极其稀缺，大家都知道民国多年抗战，战争中需要大量的子弹，而制作子弹最好的材料就是民国时期的铜币，从而导致大量民国铜币被毁制作成弹壳，使目前的双旗币极为稀少，而湖南作为重要的革命更具地，此币仍然带着革命的气息。
这枚双旗币造型精美，钱币整体规整，自然氧化形成包浆，底光柔和，品相完美，而开国纪念币是民国的开端，符合收藏学的藏头一说，藏住了民国的头，也是2000多年封建王朝覆灭走向民主社会的重要转折点，而且这枚钱币品相上乘，极具收藏价值。
古代使用铜钱不论大小，当中都有一个四方形孔眼，为什么有方孔？难道仅仅为了串钱方便吗？不是。铜钱方孔，主要是由于当时制造铜钱的方法决定的。
开始是熔铜铸钱，为此铜钱的轮廓总不整齐。为了使铜钱的周边齐整，必须用锉刀修锉。但是一枚一枚铜钱修锉是很费工的，所以就在铜钱当中开一个孔，将一百来个铜钱穿在一根棍上，一次搓成。
但是如果当中的孔是圆的，铜钱就会来回转动不好锉。因此工匠们就把当中空做成方形，穿进一个方棍修锉，这样铜钱就不会转动了，这就是古代方孔铜钱来历。
另外有一说铜钱做成四方形孔眼是基于古代人天圆地方的理念。
乾隆通宝
正面 钱币外圆内方，古人认为天是圆的地是方的，所以用上好的玉制作成玉璧用来祭天，后期发展成流通货币，可以用玉璧来购买物品，古钱币也正是由此而来，最早的古币是外圆内圆与玉璧无异，后期由于打磨容易发生转动，为了更高效的制作钱币，就发展出外圆内方的钱币，也方便固定，大大提高了制作效率，古钱币就由此而来，所以古钱币不只是一种流通货币，更是一种可以用来辟邪去恶的法器，道教就有用乾隆通宝制作的金钱剑，用来做法驱邪，圆为乾方为坤，乾坤之间四字直读‘乾隆通宝‘’表面部分产生包浆，古韵十足，开门见老师不可多得的收藏级钱币。
反面为满文造币局，氧化包浆十分明显，字体精美，包浆老旧，为开门精品古币。
乾隆通宝为五帝币之一，法力很强，又因其乾谐音，‘钱’，故有钱运兴隆之意，历来为古币收藏者所喜爱，更称之为皇帝的钱币，是用乾隆皇上命名的钱币，而乾隆皇帝是历史上最长寿的皇帝，活了八十九岁，收藏此币也有长寿之寓意，多种寓意让此币成为明星钱币，为钱币收藏之经典。
