# Worth of collectables - predatory pricing

If I traveled around the world, to collectors shops, finding a specific Coin (or other collectible object) something that had a standard value as well (such as a gold coin) and broke it (later melted it) in-front of the shop keeper, so it became known that I had destroyed 1 of the copies of this rare coin/object,

Could I measure the increase of the wealth of the coin to determine IF and WHEN such coins would become 'priceless' so that the final sale of one of the last coin/objects would pay for all costs (purchase & travel to acquire)

Edit for less ambiguity: What Economic parameters would be worth researching to determine the viability of such an endevour?

[Not 100% sure this is Economics, feel free to bump it to a different group, but I couldn't find anything more pertinent than economics]

• I mean, sure you could try and predict the increase in the value of the coin, but that would require a lot of preferences data on your supposedly rare, niche collectible. As it stands I feel like this question is too broad to answer properly. – Kitsune Cavalry Dec 15 '16 at 22:42
• I read of a known set of coins having increased in worth due to a fire in a collectors shop which the majority of the coins were destroyed/damaged, since his 'stock' was recorded, all other coin shops bumped up their prices, leading to this question. For example, the non-standard 07 St. Gaudens Double Eagle was auctioned at $7.6 million$, but the standard had 300,000 coins minted, the sale price of one of those is $1,087.38$, purely for the gold. The purchase price of an 07 standard can be between $5500$ for low quality and $20k$ for high quality. – BaneStar007 Jan 3 '17 at 5:14
