CoinTalk Members Post Coins Country by Neighboring Country in a 'World Tour' Thread
A CoinTalk forum thread asked members to post coins from countries that border the previously posted country, in a "world tour" around the globe. Starting with a 2002 10 euro coin from Germany, the posts moved through Poland, Lithuania, Latvia, Estonia, China, Tibet, Bhutan and India to Nepal. The source does not show the dates of the posts.
Correction (Oct 13, 2026): We rewrote the headline, summary and body to match the source, a CoinTalk forum thread rather than Reddit's r/coins. We removed unsupported claims about voting, a database, market and price effects, authentication and investment advice; added the missing Latvia and Estonia posts; and presented grades and other details as the posters' own descriptions. The previous headline was "Reddit r/coins Centralizes Numismatic Knowledge Globally" (Japanese headline: "コインで世界一周、国境を接する隣国のコインをつなぐリレーが話題に").
This article is based on posts in a CoinTalk forum thread titled "A world tour - post the next country." The source record does not show the dates of the posts. What follows are the participants' own posts and descriptions, not facts verified by GNJ.
Passing from country to neighboring country
The member sakata wrote that threads where people post images of their coins seem to be popular, and proposed a "world tour" of posting coins while traveling around the globe.
There are three rules:
1. Each post must be a coin from a country that shares a border with the previously posted country. The date is not important. 2. From a country on the ocean, any country across the ocean is acceptable if a direct, straight line connects them with no intervening countries. 3. A player cannot return directly to the previous country, with an exception for countries such as Lesotho, which is completely surrounded by South Africa.
sakata started the tour with a 2002 10 euro coin from Germany.
The route so far
The posts that followed went in this order (countries, dates and denominations are as the posters described them):
- Poland: Muzyck wrote that the coin was one of many the poster brought home after visiting the country in 1976. - Lithuania: 1936, 1 centas - Latvia: 1931, 5 lati - Estonia: 1928 - China: sakata welcomed the move east and wrote that Russia would open up several options, but the next post was China. - Tibet: 5 shokang, 1947-1949 - Bhutan: brass, "Sa" - India: 2015, 10 rupees, described by the poster as a circulating commemorative for the International Day of Yoga - Nepal: a gold mohar, which the poster listed as VS1983 (1926 AD) and graded MS-66
Questions about the rules
Theodosius asked whether rule 3 means a country can never be repeated. sakata replied that countries can be repeated, just not immediately.
On the step after Bhutan, sakata wrote that Bhutan borders only China and India, "So India it must be."
After Nepal, a gold square tanka of the Delhi Sultanate (AH 718, 1318 AD) from India was posted. sakata said it violated rule three, so the tour was still at Nepal.
In the last post, chrsmat71 wrote that they had not known Bhutan was a country and that the tour looked like it needed to go back to China.
