Collecting old and valuable stamps can be a fascinating hobby, and stamps from Greece between 1901 and 1927 are certainly interesting for their historical and philatelic value. Below I provide an overview of some important Greek stamps from this period:
1. **Series of 1901**: These stamps are known as the "Hellas" or "Hermes Head" series, named after the image of the god Hermes. This series was first published in 1901 and includes various values and designs.
2. **1906 Olympic Games**: On the occasion of the Olympic Games held in Athens, Greece issued a series of postage stamps with images related to the Games. These are highly sought after by collectors.
3. **Series of 1911-1923**: This period saw the issue of stamps depicting King George I and later King Alexander. These stamps reflect the political changes in Greece during these turbulent times.
4. **Revolutionary periods 1922-1924**: Stamps from this era are often marked with overprints due to the political upheavals and the establishment of the Second Hellenic Republic. These overprints make the stamps unique and valuable.
5. **Pictorial series of 1927**: This series of stamps was issued with beautiful images of historical and cultural icons of Greece. They are loved for their aesthetic value and craftsmanship.
If you want to identify valuable stamps from this period and determine their value, it is important to pay attention to the following aspects:
- **Condition**: Stamps in unused condition with original gum are generally worth more than used stamps.
- **Rarity**: Some stamps were printed in limited editions or are rare due to historical events.
- **Errors and variants**: Stamps with printing errors or variants (such as color variations or misprints) can be very valuable.
For an accurate valuation, please contact a specialized philatelist or an auction house with experience with ancient Greek stamps. Consulting specialized catalogs, such as the Stanley Gibbons or Michel catalogue, can also help you get a better idea of the value and rarity of your collection.
