这个塑料包是否能长久保存?

管他什么包装,总比银行换来的两头开口的强吧?反正是原价,先弄回来,什么时候想换包装再换也不迟

去年海军 loonie 以及 S loonie 等同样 PVC 包装方式

你是怎么知道的?自己用火烧过还是Mint网站上有说明?

因为这种 PVC 包装对硬币很不好,这是在老外论坛上看到的说法。

Storing your coins
Your coin collection should be stored and displayed with care:
.Non-precious metal or lower-value items may be kept in acid-free paper sleeves or envelopes
.Folders and albums are fine for many types of sets and series, but are unsuitable for valuable coins
.Small,
PVC-free plastic bags are acceptable for storage
.Tubes are convenient for storing circulated and same-size coins, but not valuable collector coins
.Hard plastic is a good option for relatively valuable individual coins
.Slabs (sealed hard plastic cases) are more expensive and are reserved for more valuable coins
20元小银币的包装是小capsule,好像现在美加两国所有的收藏币都会单独装到不同尺寸的capsule里,不知可以保存多久?对钱币有没有损害?

是在一个老外的钱币论坛上看到的,不过有段时间了,估计找帖子出来有难度,就是有个老外批评 mint 自己都知道用 PVC 包装硬币对硬币不好,却仍然使用在 2010 年那几款平价硬币的包装上面,于是就开始讨论 PVC 对硬币的害处了,有兴趣的同学可以到这里找找呗,肯定有帖子专门讨论这事,只是有点久了,不太好找:
比较活跃的一个加拿大老外钱币论坛

上次卷王大赛帖,一层的图就是 PVC 包装

不过听说这次改包装材料了,但具体得看收到的同学展示一下包装才知道了。
